Well, I might regret this and should have taken a break a few hours ago . . .

But I swapped out the elem shaman with a mage. The passive heals are a lot stronger than I had thought (still a little over 1k a tick) and I have 2 earth shields, so I think the mage won't be a liability. And now I have one of each armor type.

I'm stress testing by being an idiot in heroics with bad pulls and not dpsing bosses to see how much aoe I can absorb.
