DB... What to level up next?

Honestly, i wouldn't care. If you're waiting for chaos, you'll most likely get an SP reset anyway, which you can use to reallocate your points where ever you please. at this point you're better off just getting as many points as possible to reallocate later. Raid is meh, CoH is cool for bossing i guess, mirror target you don't really need, if only for the passive bonuses. you could just level suddne raid to pass the skillbooks so you can insta dump the points into those skills later without having to go get books (which would probably be more expensive). pick your poison i suppose.
