Some classes have become too overpowered

Fire is very viable. Dotting an entire enemy team applies a lot of pressure and "wastes" mana or forces them to completely disengage to go drink a potion, which gives your team plenty of space to push in. Being a good BLM is recognizing when you should be in ice and when you should be in fire, and it's a tricky thing to get down pat. Ice should generally be your default state, though.

If you're using fire you're wasting everyones time. The mass CC from ice is way way more valuable.
