Rather than starting a new thread, maybe I can get some advice/help in this one.
My threat isn't an issue, most of the time. I stay very well above the dps in my groups and raids. The issue I have is keeping up with the offtank threat, specifically on Patchwerk.
Every time I'm designated the MT for patchwerk, a warrior is designated Hateful tank. For the first minute, minute and a half, it goes as planned, at which point I can't keep up with the warrior threat, and roles get reversed. Is it most likely an issue of the warrior having better gear, and therefore better threat generation? Or do warriors just put out generally better threat? I don't have a WWS for any of the patchwerk fights i've recently done, but I can say I'm using a 969 rotation for threat, and this is the only fight I have any problems with.
