Hopefully some of you who are reading this are in the Mists of Pandaria Beta! If so, lucky you!

I just have a few questions I thought I'd shoot off so I could check back later and appease my craving to play this expansion :)

So Dark Bargain will absorb all damaging spells/attacks and then deal 50% of that damage over 20 seconds in the form of a shadow DoT?

Could Twilight Ward and Unending Resolve be used in combination to effectively negate most of that damage?

How useful/effective has Harvest Life been in PvP? Would combining it with Mannoroth's Fury allow it to be a decent option?

What are you Demonology Talent builds? Also when you choose your talents what are you focussing on? (PvP, PvE, SingleTarget, AoE, etc) Are we seeing any cookie-cutter combos arising?

Is there any hope that the lesser demon spawned from Grimoire of Service will be slightly more controllable? To a point where I could make one two Felguards use Felstorm on the same target? I've heard the AI for demons has improved quite a bit and would like to know more.

Generally Warlock information and statistics are welcome!

Thank you in advance :)
