My job is guild OT for our 10 mans so I focus'd on a build that brought good dps as well as tankability. I'm running a
13/50/8 build that I like very much. Can tank anything and can pull 3500 dps in naxx 10.
Tanking:
Single - IT,BS,IT,BS,IT,IT,IT FS on KM proc
AOE - DnD,IT,PS,Pest,HB,BB FS when able
Single with adds - IT,BS,IT,BS,IT,IT,IT FS on KM proc HB when adds join
