I haven't touched Revenge for the first 50 levels of my Barb, but thought I'd give it a try now that I'm in Hell diff. Seems like a worthwhile ability with the rune that gives a 30% proc rate, but I feel like I'm just staring at my skill bar to see when it procs. I haven't been able to notice any on-screen indicators central to my character to make using this ability more readily. So, is there something I'm missing? Would be great to have some kind of indication other than the gilded lining around the ability icon.
