The healer DoTs are isolated too. My present expectation is that they'll fold both the DoTs into one and rework Iron Jaws. Possibly into something meant to make Army's Paeon less lame. Having a DoT in your priority system job is perfectly fine.

Sidewinder as just a damage button is also fine; plenty of jobs have them. I'd like for it to be sexier, like an auto CritDH or something, but there's nothing really wrong with it as is.
