[PvE] Warlock 4.3

Didn't see any Warlock threads except for 5.0 and a PvP one, so here we are.

Does anyone know of any good guides for demo locks? Friend of mine has been looking, but can only find Aff/Destro, and was wondering if he should respec. I'm not well versed in warlocks, so thought I'd check here since I know a few of you have locks (theck for one.)

Start here as it should be updated for 4.3
