I will try to simplify things a bit;

MRD: Warrior - A reliable good DD that can Tank as well at the loss of damage.
THM: Black Mage - Boom
CNJ: White Mage - Cure
GLA: Paladin - A top notch Tank, can hold hate like no other.

(The thm/cnj thing is just a stab because I know how these forums like to bicker about them. Either way, idc how they go about it. cnj/thm = 50. So I'm fine with either)

Ever looked at a lvl 50 THM's naked Mind vs a CNJ? Just curious~
