yeah but raids are totally truncated in 14 as opposed to wow how many healers are healing in wow raids as opposed to in 14? So yeah you may not heal as much but the responsibility is probably split x fold between x more healers, i doubt youre going into raids with just 2 healers.
and blu would have to be made a bit differently than traditionally to fit in 14 i can see some job quests made out to learn signature moves like white wind, and i can see them making it a tank cause the whole idea of a blu is to get hit and survive the attack to "harness its power" albeit literally meaning to permanently learn it, in 14 itd probably have to be different imo
