I don't get the Siphon Life change hate. Any Warlock that's interested is going to have the Siphon Life talent. Any Warlock that has Siphon Life is going to have the Corruption-boosting talents. You're stacking for a single spell that delivers twice the goodness. In PVP, this spell is going to be even more brutal.

It's mostly about play prefrence, I liked the complicated dot managing of afflication past, and I wont really be able to see if SL and an affliction build would be better than the one I have now until I can test it in a raid situation, and the ways its looking that wont be for a while.

It's a little bit of a nerf to drain tanking though, just off the top of my head.  I haven't actually looked at the math, but my gut feeling is this indirectly nerfs the Soul Siphon talent.  It's one less dot, thus lowers the return on health by roughly 3%.  I haven't gotten around to checking to see if the 40% of the corruption tick after being increased by 5%, returns more or less health than the 3% that is lost on Soul Siphon.  Of course I'm talking about self healing but the same numbers apply to damage done, which isn't really what you care about when drain tanking.

But Skree is right, it's mainly play preference.  I'm enjoying Destruction again lately.  It's nice that it's viable now, and has gotten to be alot more than just spamming shadow bolts (to over simplify a little).
