Goodness, you need something else to take up your time. Lol at hunting down my server forum; and no, it was only a couple weeks ago, not a lot of campaign, post 1.3 debuff and sinTank nerf, and the second sin is even less geared than myself. I'll tell you how it goes on 16 HM after tonight. Even then, as the other poster said, you roll with a third tank so you could have hard bubbles like Deflection up every time. We've also done some NiM but it was a long time ago and I didn't care enough to post it. The point remains, people are still doing it with SinTanks, without a ton of problems.
Next time try to be a little more condescending, I think it would get your point off better.
