The Klaxxi "Raining Blood" buff doesn't stack as fast as it used to. I could reliably make use of it before, but today 85%+ of my kills happened before reaching 8 stacks of the debuff. Kinda sucks as it makes it a pointless buff now. There seems to be an internal cooldown of some sorts on the debuff now. Before I would get 2 stacks of the debuff when using Glaive Toss, only got one today.
