It also effects vendor gear...so choose wisely

I like rangers with 1 in warfare instead of pyromancer to get executioner take glass cannon and get hydrophorics for combat control and get soooooo much ap in 1 turn

Useless section in this game. Literally has no impact in the game. Pick any class change abilities the way u like and go into your adventure. U pick Warrior and build him as Mage, Archer and make his as summoner and so on. Nothing changes in the entire game.
