Well, as a tank, I will say this. When we do big pulls, it's very hard to see :P I normally keep all the mobs on me, but it's not hard to lose track of one. Especially if the healer is spamming heals (which they should be on big pulls honestly). Then to top it off, if DPS are killing slowly, as a PLD, I can run out of MP before they kill the majority of the mob. PLD's really need more AoE T_T
