Summoner should use their summons to deal dmg once then dissapear, they should also be able to use dark magic

Scholar skills should only identify mobs weaks points and nothing else

Dragoon should also be able to use shield

NiN should have the ability to throw items from inv to dmg the enemy

Dark Knight should also be able to use White Magic

i can keep going if u want



NiN in ffxi was made a tank, if that can happen i dont see why Dark Knight cant be a tank in FFXIV.. heck it even makes more sense
