Just to disclaim that I consider myself still pretty amateur as a warrior. I share hoping that I can contribute positively to this community as I had benefited from some of the discussions here. Here are my views:
This is something I notice. At above 510 gear level, gear choices really make a difference. Me and my other guild warrior is about the same ilevel but he had (now no more) slightly better weapons and different trinket choice and he pulls ahead of me. Eg straight forward fight like Jin Rokh he'd pull near 190 and I would pull 176-180k. I'm beginning to think that twin consort trinket kinda suck as the stacks build up very poorly. Jikun feather appears to be really strong. Talisman of Rage proc is hard to time and luck plays a part to align it with BB .
In terms of melee standings, our guild best melee is actually Eunya, a Monk!? Consistently ranked ok all fights and even beats his sim dps. Salure our rogue beats me in absolute DPS but never ranked. Deathshatil a DK has insane dps on some fights but I've beaten him on Jin'rokh.
Bottom line is: at a certain level, it comes down to skill and personal gear research. Above 510 ilevel, u got to experiment with gear pairings and not just rely on simcraft / mr robot anymore.
