Never having played a tank, I was curious if any of you have put any thought into having a tank hold aggro without using sunder? So a rogue could expose for the 52% armor reduction. Rather then just stop sundering at a certain percent (75%?) and letting sunder reset/bump off, would you think it is possible for a tank to start, and maintain aggro throughout an entire fight without using sunder once?

Also, would this be possible without the use of Shield Slam?
