I have to agree that Broil is broken (can anyone argue otherwise, really?), but I can't agree with it draining more MP than it costs to cast, that would make the skill completely pointless. My main problem with it is that unlike WHM's and AST's nukes, Broil has no real counter except "don't even be in a SCH's line of sight". Slow and Heavy are both subject to immunity after a hit, and can be negated by abilities like Concentrate. Broil needs a similar counter (maybe an immunity to MP drain after a hit to be in line with other enfeeblements?), or reduce the MP drained to 500, but in this case the casting cost would need to be tuned down to 250.
