The problem is, that the as the game is dumbed down, to enable it to be more accessible to players new to mmo's granting healers far more healing ability than they would normally have. When translated to a pvp enviroment this becomes a huge imbalance and highlights the issues with the each class as a whole. Im not sure how it will be possible to balance a healer for competitive pvp combat whilst enabling them to stay functional for the pre designed pve content. Many people say that ff14 simply wasnt designed for pvp, and it was thrown in purely so it wouldnt be missing the feature, so its easy to see why it is such a mess at the moment with little hope of being resolved. It is a shame though as the pvp setting of frontlines could be alot of fun.
