The other thing I have to think about is that learning Ulduar 10 is a lot easier with 3 healers, or so I hear. I may switch to bringing Spec (there are some upgrades for him there), or strong-arm one of the dps into healing.
Shh... you weren't supposed to let Eric know about The Black Heart.I would agree with your assessment of Allanon, poor guy hasn't seen a drop in some time. He could definitely use some love BUT I am open to reg and h-toc with him to get him equipped. Bass (our other possible tank for Naxx) got two sweet pieces (black heart is one of them) from toc yesterday.
