ere's a list of tanking plate blues & purples from level 80 dungeons & 5-man
heroics, as well as equivalt rep rewards.  There's another item level down that
has stuff we might still use going into Naxx, but I don't think it's worth
explicitly seeking it out.  Note that some of these are craftable BOEs.  I didn't

include badge gear, this list is mainly for knowing which dungeon to run.

Druids are welcome to add a reply with leather tanking gear.  :)
