Threat Generation/Degeneration DPS Options
I just joined a new casual raiding guild, we're doing ICC 10 and just down Saurfang last week. I was brought in for Arms dps specifically and to help tank the eventual 25 man raids since all our other tanks are pallies.
I'm just about at the hard cap for ArPen and I'm running into the issue where I'm riding the tanks' butts. I'm concerned that once my gear improves I'll basically have to start deequipping my weapon. Now I'm wondering if there are any steps (other than going fury/cutting my rotation short, those are obvious but don't really solve my problem) that we as a group might be able to do to make the threat gap a little bigger. I'm considering asking one of our hunters to maybe train up a worm pet to take off the sundering threat, but I'm not sure if that would make a big dent in his own damage that would outweigh the benefits.
I'll probably end up getting subtlety to cloak since every little bit counts, but I still wonder if there are any common stumbling blocks pally tanks might fall in to that if corrected would increase their TPS, I only really know about warrior tanking and TPS, but I do know that my threat isn't as big of an issue with many other tanks.
Any help or suggestions/insights would be appreciated.
