Honestly thought this was a troll thread to start out with too...

Acc has been around as long as Str, Vit, Int and the like before Final Fantasy came along and the only reason it wouldn't be in the game would be if the battle system is something like XV. Really if there was no Acc there would be no contest as to what stats each job would need (take Dragoon relic, crit and det for days) but with it yes, it does indeed add a bit of complexity to how you gear yourself. Removing it would probably require also making endgame enemies have higher def/mdef/more hp since hey, they will always be hit!

Also you have to remember, if Acc is removed, so is evasion which also removes certain skills (not all, but some). So it would be a little more than just making everyone hit their target.
