I was in Ulduar-10 last night (my guild only runs 10's) and main tanked up through Hodir. We've had these bosses down for a while now, and tonight I really noticed significant rage problems thanks to lengthy avoidance streaks. At the time, I was the standard Ulduar 5/15/51 spec, which may seem like overkill, but really isn't when you're doing 10-man progression in 10-man gear.
In an effort to combat the fact that I was having really streaky rage generation, I switched my spec to 8/10/53. Since I know I don't need 5/5 Imp Demo Shout (that's only for Heroic Vezax), should I be using a more standard Deep Wounds spec instead? Or will that hurt my survivability too much?
I worded that title very badly, I think. I'm hoping that pushing up the threat generation in my spec will make up for the fact that I'm having rage issues on a lot of the content. However, I'm worried about Mimiron, Vezax and Yogg in terms of survivability if I do so.
ETA: I know it was streaks, rather than pure gear-based issues of the kind I started having in Naxx-10 toward the end, but it seemed to happen a few times on every boss last night, which was worrying. I don't gem for avoidance, and my avoidance enchants are mostly necessary def enchants, so there's not really anything I can change there.
