It's more of a case you not knowing how to be a BLM in PvP, then trying to blame it on something other than yourself

Black mages can be an amazing class in frontlines if you know how to play it, but you also have low hp, which means that other than the healers, you are going to be the focus because (unlike the healers, who are the tanks of PvP) you cannot tank damage to save your life

Also, how in any shape or form is Frontlines like Wolves Den? >_>
