Very weird catch22atplay,
World of Logs - Real Time Raid Analysis
I picked a 217 seconds Auriaya fight, where i had a decent 6,5k DPS (while also being the sunder armor bitch) and got the following results instead:
(This was the latest most representable bossfight I could find, as it's as close to tank&spank as it gets)
Glyph of Heroic Strike: 220 rage
Berserker Rage Effect: 140 rage (0,645 rage / second
*without including the extra rage gained from damage with BR up)
Bloodrage: 100 rage (Instant rage)
Bloodrage: 43 rage (non-instant rage over 10 seconds)
Rapture: 8 rage
IBR still seems a strong choice per talent point. "1/1 Anger Management + 1/2 IBR" seems to be the best choice though as it would've given 72 rage over 217 seconds (0,333 rage/second) from anger management alone, which is a slightly better number than IBR per talentpoint. Guess I'm off to respec then.
Edit: Analyzing my log further, I don't seem to prioritize slam much over BT often (and definitally not over WW), which should be okay since BT does slightly more DPS anyway if rage is not an issue. I don't seem to prioritize BR over slam though. So my DPS rotation should be representable as well in that log. (Don't mind the other bosskills in that log though, the Thorim log was made by the tank in the gauntlet (while I was in the arena) and on Freya I had roots and trees duty.)
