I've been playing around with unholy lately, and I've noticed that I generally end up with 3 locked runes, and they are completely locked for a few seconds before the cooldown to refresh them starts. From what I've gathered spending runic power helps speed this up, but for me it just feels really jarring cause I can't refresh outbreak etc etc.
Does anyone else have this problem? Maybe I'm just doing the rotation wrong but man I just don't like it if this is how it's supposed to be.
