You ruled out some important facts Meto..
*Knights have their HP, hard to kill and are mostly used to block quests, go defence in battles and shit like that that makes ppl survive (They arent killing machines)
*Pallys are a combination of a knight and a mage, they have decent hp, do decent dmg and heals decent. They can also stay at distance..
*Mages do alot of dmg but when theyr mana shield is gone, (something u can do with just 2 other mages or pallys for that matter) theyr dead..
So every1 just find the vocation they belive is best and stop wineing ffs!
