So, I just got my four set last night (hazaa!) and it made me really start thinking about enrage uptime and how to absolutely max it out (as opposed to doing the best rotation). Figured I'd start a discussion on here. This is what I figured out so far. Everything is the maximum (no overlap/mid-duration-refreshes of enrages) and the math is rough, so let's do this and figure some shit out!

Assuming ~20% crit, one out of every two and a half bloodthirsts will crit. In 60 seconds, you can get off 14 BTs, so assuming the enrages never overlap, that's a maximum of 14hits*(1crit/2.5hit)*6 second enrage= 33 seconds enraged, or right at 56% uptime.

Let's say you got a weak aura telling you when enrage falls off, and pop Berserker rage whenever it does. You get two of those every minute. If timed right and again, no overlapping goes on, you've got at most 12 more seconds of enrage, upping 33/60 to 45/60, or 75%

Alright, so you have a recklessness every 2 and a half minutes that guarantees 100% crit chance on BT for 18 seconds. That's 4 BTs (if you're quick), and 18+6=24 seconds of straight enrage. That leaves us with 36 seconds of the original 75% uptime, which would yield 27/36 seconds enraged. In all, that minute you'd be enraged 85% of the time.

That's as far as I've gotten though, 75% consistent uptime and 85% every 3rd minute with Reck pop. Any other ideas? How close could we potentially get right now to 100% with the gear that's out there? I'm thinkin crit procs but am at work and can't go any more in depth.
