I think the main reason behind Infuriate now having charges was to help reapply Storm's Eye as late as possible. If your Storm's Eye is running out in 5 seconds and you just used Maim, there's no time to use Storm's Path and get to Storm's Eye again before the buff runs out. But there's enough time to fit in a Fell Cleave or two and then use Storm's Eye just before it runs out as opposed to refreshing it 5 seconds too early.

What bothers me is that this is the only level of complexity that gets offered to the Warrior, and it doesn't even have that much of an impact. You could literally just alternate between Storm's Eye and Storm's path and use Fell Cleave when your gauge is about to overflow, while making sure you used IR and Upheaval as soon as they're up. This is as mediocre of a way to play Warrior and you still end up doing tons of damage. There's just not much of a difference separating this playstyle from one that carefully monitors their Storm's Eye buff to make sure it's applied as late as possible.

What I'm saying is, I just wish there was more complexity to our playstyle. One idea I have is that, the closer Storm's Eye is to running out, the more damage you do. Capping out at like 10% more damage when it's at 5 seconds before it's gone. Don't even really care if potencies get adjusted. At least this would give us something else to focus on while waiting for our Inner Release to come back up.
