Build power changes are part of engy mod, t3 engy got buffed, now it has more build power (15->30 for uef/cyb, 15->40 for aeon/sera), as well as t2 engy (10->12.5 for all factions)
veteranicy system was changed very long time ago, but still in FAF ofc, instead of kills we use experience poits, you get 1 point for t1 unit, 3 points for t2 unit, 8 points for t3 unit, do not remember about ACU and exp units
there are TON of different changes they all now in FAF wiki
http://www.faforever.com/mediawiki/inde ... hange_Logsedit: also those changes does NOT include enother ton of changes made by 3604 patchmod of gpg net (i beleave faf balance was based on those patchmods, but i can be wrong)
