tone down fireball a bit.

[Lainge]

fireball is just way too good to not pick now, i think a cooldown extension would be good, like a 1 and a half minute cooldown.

also fireball sets people on fire even if they are wearing firesuits, and rolling on the floor saves you better than a fire extinguisher during the stun.

It's alright, Cthulhu staff is better in my opinion.
