I was originally going to write this week's Blood Sport on the myriad of PvP changes on the PTR. However, I found myself writing a large amount about one subject, so much that it deserves its own post. Warlocks are losing Drain Mana in Patch 4.0.6. I'll get to the other changes some time soon (Blizzard is still not finished releasing changes at the moment). To summarize what is about to be a very long post, I don't agree with this philosophy.
No sir, not one bit.
I'd like to know what kind of problems Ghostcrawler is referring to. I don't know anyone who thinks Drain Mana is an incredibly powerful ability right now. Does it shorten games? Sure. That's the intended effect -- or so I thought, anyway.
