Playing only DPS in XIV but healer in other MMOs really shows to me that XIV players really aren't mmo players.
I am so used to DPS in other MMOs helping out through buffs, mitigations and aggro control but in XIV they literally just DPS, Its pretty boring. When im on Monk doing extremes in PF I often ask the healers if they have points they want me to use Mantra at and they're always suprised that I even use Mantra let alone talk to them about it. Also no one talks about who mits first between casters, melees and phys range so they don't overstack each other even in savage. XIV players honestly take the Role names completely at face value, DPS need to DPS, Healers need to Heal and Tanks need to Tank don't do anything else.
