If you want it to work the way it used to, you can change this line in /zone/attack.cpp:
Code:
chancetohit -= ((bonus * chancetohit) / RuleI(Combat, ChanceToHitDivideBy));
To this (replace the above line with this line):
Code:
chancetohit -= (bonus) / 10;
I actually do that manually every time I update my server. Otherwise it would mean a huge headache trying to rebalance everything and I just don't have the time to do that right now. I am sure you could also play with the ChanceToHitDivideBy rule and probably get things mostly back to normal. I just don't know what you would want to set that to, since the calculation just works different now.
For the new AAs to work, you will need to update your AAs table from PEQ. Otherwise, you will be missing a large number of AAs. If you haven't updated in a year or 2, you might have 100+ AAs missing that you could be using
