Dude this is a tremendous ignorance! Lemme be extreme a bit...so you mean that if we had 1 mage class, 1 melee class, 1 ranged class, 1 gatherer and 1 crafter it would be a better game...i'm just removing options you see? Its just a nonsense, man!
People is differente...so the more options you add the better the chance of everyone finding something they like there. I'm all up for a better balancing regarding old system...i'm still trying to keep hope up regarding battle team noticing they can do it perfectly....after all, as FFXIII player, i know Hope is always the last one to die! (sorry...but i just love this phrase! lol)
