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.

"Very viable"? This is not SCH, applying DoT to whole enemy team is a whole lot of time and resources for weak DoT instead of disabling the whole team or help picking off key target one by one. You dont want them to use pots, you want them dead. I think i dont have to tell you what can prevents them from escaping.

When it comes to most situations, Ice is the obvious way to go, that is called "very viable". Don't hide behind "good BLM" blanket argument, every decent BLM on the planet already knew that Fire is weak and a huge opportunity cost. Its a huge choice to make, not a standalone skill.

'Has some uses' doesn't mean "very viable".
