In non-hero battles I am having a very hard time keeping threat and an even harder time building rage. Last night in Tol'vir on the 4-5 man groups I could not keep all of the threat on me. Although on of the char's was a ilvl353 that just wanted to run through quickly, we still had a tough time. I reforged dodge into Mastery last night and have not had a chance to test it yet, but before I reforged my percentages were 11%, 12%, and 40%. Should I get rid of deep wounds and go back to shield spec to generate more rage?
Rest of the group was boomkin, priest, rogue, and DK.
Get rid of that deep wounds talent and pick up shield specialisation, you'll suddenly be swimming in rage and able to perform way more actions than before. Get better suited glyphs (cleave, shockwave, thunderclap) for your aoe tanking job and have your rogue give you tricks while the owl give you thorns on the pull, aggro shouldn't be an issue after that. Marking one mob to be focussed down while you build up enough aggro on all the other ones via shockwave/rendspread/revenge/cleave to keep up against starfall/hurrican and howling blast.
And please get a full set of glyphs - missing a third prime (devastate) and two minor (demoshout, berserker rage) really hurts.
There's nothing wrong with cc-ing one or two mobs even in a normal run. I don't understand why people object to it - it's more fun, it's easier on the tank and also easier on the healer's mana. On my healer, I heal heroics and raids and am fine, but in normals I need to keep drinking because people have already stopped bothering with cc one month into the expansion.
I'm saying this because it will also make your tanking job easier. Mark mobs, tell everyone to focus on the skull and then on the x, and after that you pick up the cc-ed mobs one by one. Cata dungeons are NOT meant to be "charge in and tank everything at once" style groups anymore the way they were in Wrath.
Thanks, I respeccd and rage is no longer a problem. Also picked up a few glyphs and waiting on a guildmate to make the others.
Now we just have the problem of the priest (holy) running oom 70% of the way through fights, but that is a topic for a different group
