Imo, Ivycloth of Stamina>MTB for BiS Warlock.
Perhaps if DPS wasn't so weak atm, then maybe it would be viable to stack more Int/SP.
However, in the current state of things, I believe Stamina is the go-to stat for this class.
Also, Hit is strange. With only GSoJ and hit boots, you're left with a .5% chance to miss on 20's. Out of all the games I played tonight, I only missed a few times, and it was only on lvl 24's. (which makes no difference even if you are hit-capped) Maybe I was just lucky, idk, but it could possibly open up the cloak slot for a better choice other than Lushwater.
A few personal notes:
Demonic Leap is amazing. It's like the Goblin racial on a 10 sec CD. This spell has sooo much potential.
As far as talents go, Dark Regeneration is a tough one to beat. Losing Soul Harvest was a huge blow to our survivability, and even though this new spell is on a 2 min. CD (which really isn't that long, considering how long fights are atm) this spell still gives you a good chance to live. Using it with HS for example, I've managed to get a 1k heal crit.
