Every week, WoW Insider brings you Blood Pact for affliction, demonology, and destruction warlocks. This week, Megan O'Neill wants Drain Life filler back despite knowing it won't happen.
So you just boosted your warlock to 90 and... You decided that playing destro at 90 isn't for you, but you still want something easy to pick up.

Due to Soul Swap, everything is a single target to an "aff'lock."
But I'm getting ahead of myself.
