I believe this feature was removed in patch 1.11 (which wasn't released). Should be included in the readme for the patch file somewhere.

Not that I can tell. I don't really see why it should be to be honest. I'm generally happy with the combat model as it stands now. The 4 die roll as discussed (frequently) introduced alot of imbalance, mostly as far as intra-(not inter)era combat went.
The example provided is mostly just bad luck. Occasionally you will get a streak like that even randomly. I'm ok with that. You will get an opposite 'streak' now and then that benefits you as well.

There was such an outcry from the community against this, with plenty of statistical analysis showing that it would adversely affect same-Age units to an astonishing degree, that it was abandoned.
It's also important to note, if you go back and read the original language, this "fix" was intended to remove the "perception of streakiness" in the RNG.
The RNG is about as good and random as you can get from a computer RNG. The human mind is designed to detect "unfortunate" patterns (as well as anomolies)- you don't complain when you get a string of victories with horsemen vs. fortified spearmen in cities, but if the AI were to win 3 in a row or more in the same fashion, we'd be decrying the RNG.
It's all about perception. There's nothing wrong with the RNG as repeated tests have shown, and the proposed fix had nothing to do with fixing the RNG - it was all about "fixing" the player's perception of the RNG.

I don't think they need to attain that particular objective.
The "problem" was that players perceived the RNG to be streaky. The best way to address that is to educate the players in regards to Pseudo-Random Number Generators, human psychology in relation to patterns and anomolies, and statistics.
So you occasionally get a super-spearman that defies logic, so what? Random numbers are just that. If there's a .01% chance that the oldest unit in the game can defeat the newest, guess what that means?
It means that it's possible for a spearman to defeat a tank on any given combat round.
Not bloody likely, but possible, and when it happens, you take notice because it is anomolous - that's human nature. I don't think the combat system needs changing, really. I'd much rather see programmer times spent making the AI a bit more... intelligent, less predictable, less manipulatable.

since we are on the subject of RNG's, can someone expain this to me please?
How do random numbers factor in with the Attack & defense value?
If everything depends on the RNG, then why have attack/defense values?
As i understand it, a fortified spearman in a walled-town (100% bonus total), would have a defense of 4 points (2+100%). Assuming an attacker with a strength of 2, how would you calculate that?
I suppose you would get a % value (what is that equation?), and how does the Random number go with that %?
Thanks for any help!

A & D values form the basis of the combat system. Using your example, a fortified spearman in a walled town (assume grassland) would have a defense of 3.7 (50% bonus for walls; 25% bonus for fortified; 10% bonus for grassland -- 85% bonus to base defense of 2 means 3.7 effective defense). Assume an attacker with its "2" A value (let's say an archer to avoid discussing retreat chances of the horseman).
The basic combat calculation for an attacker's chances in each round of combat (each HP) is A / (A+D) where "A" and "D" are the effective values for the participants reflecting any bonuses available to their base values. Obviously, a defender's chances would be D / (A+D).
In our hypothetical, the basic value would be 2 / (2 + 3.7) or 2 / 5.7 -- in percentage terms, the attacker would have a 35.08% chance of success in each round of combat.
In order to determine whether the attacker wins or loses an HP, a random number is generated by a random number generator (RNG). Common computer RNGs work on a scale from 0 to 1023, meaning a possible random number from among 1024 possibilities. The RNG result would be compared to the probability of the the event that "calls" on the RNG -- in our case, it is one round of combat between our 2 attacker and our 3.7 defender. Our attacker wins 35.08% of the time. 35.08% of the possible 1024 outputs of the RNG is 359. Our attacker will win an HP if the RNG returns a value among the highest 359 possible outcomes of the total of 1024 (could also be lowest -- main point is that it is 359 of 1024, or 35%). If the RNG value returned is 665 or higher, the attacker wins; if 664 or lower, the attacker loses. Each HP requires a new random result from the RNG to determine whether the "odds" were met or not for that specific event.
In our example, assume that a vet attacker lost the battle, but managed to knock 2 HPs of the defender -- all told 6 HPs were lost, meaning that 6 "calls" were made to the RNG. The RNG output and practical in-game output might look something like: 879 (A win); 650 (D win); 1102 (A win); 600 (D win); 124 (D win); and 273 (D win).
It might be helpful to think of it as: (1) A vs. D sets the odds; (2) the RNG is a dice roll to determine whether the good guys (you!) beat the odds.

Actually shouldn't it be 18.5D? 10% terrain, 50% walls, 25% fortified = 85%... each cav should have a good shot (1/3ish) of running away, but only about 7% of winning against fresh vet infantry. I've not often seen 30 AI cav attack, but if it were to happen, it should be ugly for both sides. Bad luck on your part.

Furthermore, things are made more complex again by the observation that luck tends to continue - the random numbers are not totally random, and so if you have been experiencing bad luck the trend is for that to continue for an unspecified number of random number rolls. |
Is this a specified/tested bug with the RNG or is it merely just frequent player(s) observation? Randomness does not mean its required to pick a totally different number every time. It is required to roll randomly. Every number is therefore an equal shot of rolling. Just because its statistically unlikely doesn't mean it can't roll the same number for a good long time. It goes in clumps sometimes, and you'll feel unlucky. Sometimes you'll get a clumped series of good rolls as well and feel supremely confident. Those are the breaks. Anyway, I believe this entire argument has been made in full from both sides when the proposed changes were first suggested and it seems trivial to continue it when the change has been dropped in the fury of public outcry.

hmm.. can i bug you guys with one more formula?
How does experience factor into the 'Odds' calculation? Now i realize experience gives no bonus, except hitpoints, but how would you go about calculating the extra chances into the overall odds of winning?
Example, Modern Armor (24 attack) vs Mech inf (assuming with all modifiers applied, Mech defense = 24). Now as i understand it thanks to you guys, on each roll, the odds are always 50% for each unit. But lets assume the Mech were Elite - according to the combat calculator from theseus, the odds are now something like 77% to 23% in favor of the Mech Inf (obviously, since it has more chances to fight). But how would you go about calculating that on paper? 
Thanks again for any help |
The experience is factored in with the HP's. If you run wiht 24 for A and D and no bonus the out come is not clear unless you use 100 for trials. Now the defender does well,but making it elite increases the def winning to close to 70%.
The problem is that you need to run it bunch of times to get a smothing. You can do a run, then another and see wild swings.
Making the trial number larger leels the out come.
Basically you need another roll if the unit has experience over the combatant. If you are a regular and go against a conscript you have an extra round. If the gap is wider you get yet another round. So elite vs reg gets two extra rounds if needed. This is why barracks are so useful.

I got hosed.
You'd get the credit from my PhD supervisor though, for being the more thorough of we two. About all my post would be good for is secondary school teaching.
thx theseus - but i don't think i'll be alt-tab'ing while playing the game
