OK Djaeb Im back after some testing, I didnt use any addons or number counting devices so its all from just what I noticed.
Caulfield, lv1 human Warrior. 138ap, 30 strength, 45% crit, 10 haste gloves & 5 hit boots.
First I tryed some duels in goldshire, but results are not very conclusive as there were not too many people around to duel and when I was dueling, we were jumping around so I was able to concentrate on the rage bar/cd/and duel all at once, sorry ):
Next I went to hogger with a mate, First I tanked him and had him hitting me. No matter which of my main three weapons I opted for I was always capped at 100 rage. So if a lv1 raid team was to somehow have a warr tank, he wont be starved of rage at all, the warrior will be . . . Furious haha.
After that I had Lovestotwink's lv10 rogue grab aggro at the start of the fight, and I swang at hooger from behind. 1st I used
Keen Machete - Item - World of Warcraft w/ LStealing, and it had disappointing results ): the 3sec Strike CD would finish while I was still at 10-15 Rage most of the time.
Next I used
Venerable Mass of McGowan - Item - World of Warcraft w/ sader, but sader didnt proc much so dont need to worry to much about that. Anyway this came in about right on par, Strike's 3sec CD would finish while my rage was at 18-25'ish. Lastly I tried
Reforged Truesilver Champion - Item - World of Warcraft with 20haste and this regenerated rage at an awesome rate, my rage wasnt going down much at all, it was actually going up over the course of the fight.
Lastly I tried hitting at a 19 twink paladin. Results were worse then Hogger. Keen Machete left me waiting for ages between each Strike CD, and Ven Mass of Mc'Gow wasnt able to spam Strike either, although rage regenerated quicker then KMachete. This time the 2Hander PvP BoA sword came out ontop again, I was able to use strike every CD.
OK from this I think I'm able to conclude that rage is generated on DMG done not on Swings that strike your target. Also when attacking things of higher levels the proc rates seem to go lower, so 20haste/25Strength is most likely better. Perhaps maybe the best rotation would be use a 2Hander with 20haste till you rage cap, then switch to sader and hope it procs while your rage slowly declines, then upon procs pop LBlood & switch back into 20haste, similar to the hunter method except 25agil becomes 25strength or 20haste. But the move Strike hits very weak anyway, maybe its not worth the effort. On the Theramore target dummy it didnt crit over 30 for me, while white hits passed 250 on crit(with sader).
Well thats about all I have to report atm, maybe you can break down the data in a different way to me. Cheers.
