Save it. Warlocks have been on the nerf end of the scale nearly every patch since the TBC release. I know Shaman are in a sad way, but seriously, ragging on how OP Warlocks are got old over a year ago.

You sound like my mother.

I know it got old awhile ago, but it's the frakkin truth. Even with the warlock nerfs, they're still extremely well balanced and well taken care of. Shaman continue to be ignored and tossed to the wayside. This small buff is just another notch in the belt.

Mana drain effects are now affected by resilience.

400 Resilience reduces mana-drain effects by 20%. This means that warlocks will drain only a tiny bit more. The big people who are affected are priests and hunters.

Ehhh...it is a buff, but with extremely limited use. I haven't noticed Warlocks mowing people down as much in the last few months. Truth is that this increase would be a game winner one in ten times--and maybe not that often. We all agree that Shaman can use some love, but Warlocks play this game too and they have been getting hit with the nerf bat pretty hard for a while now. I can immediately think of about five things that are OP on other classes that should be of more concern than this trifle.
