Why didn't 4th Job AoE's get a cooldown?

Heaven's Hammer (maxed) has a 70 second cooldown, the same range & similar damage, but can never kill the monsters. It still takes 2-3 seconds to cast. Is that balanced?

It is when their single target damage far outweighs that of a bishop/mage.

Lol, so the fact that the top 50 is almost entirely Bishops doesn't mean anything?

They're getting the highest %/hr by nearly double what any other class can get.

Bishops are by no means a bad boss class, either. Ever try bossing without Bishops? As a class who will only ever go to Horntail because they needed someone with Stance to be seduced while everybody else attacks, I'm just a bit envious of the Bishops getting HS, Bless, Heal, Dispel, Resurrect, Invincible, Elemental Resistance, Holy Shield, and Mystic Door.

Ever try bossing without an attacking class? Bishops are there for bosses for support, and that's it. They might train twice as fast as other classes, but they deal damage to bosses twice as slow. That's how the classes balance out.

Bishops have an edge over mages; its hard to argue against that, but comparing mages to the other classes is pretty cut and dry.
