Is that going to change? A discussion on the forums leads to Ghostcrawler revealing that yes, they are considering allowing Bloodlust/Heroism be a buff one can gain through an item. Now, I'm torn. On the one hand, NO! Keep your filthy crafter fingers off of my precious! My precious! I'll kill you! I'll kill all of you! But on the other hand, it really isn't fair at this point that Bloodlust/Heroism is pretty much the only buff we can't get a lesser version of through crafted items. A 25% speed increase for 30 seconds (or even 35) would be weak enough in comparison to real Bloodlust that you wouldn't have to worry terribly about being replaced by a drum kit. I suppose. Man, I don't want you to have my Heroism. Like I said, I'm torn.
So what do you think oh why am I even asking we all know you want my precious. My precious!
