The idea of TC always criting to apply deepwounds is nice but most progression tanking don't take the talents due to us needing lower CD's. The idea here are flowing around the sense of how we have to spec and glyph for a certain type of fight while other classes don't. The deepwounds build is nice for AoE but when you are dieing it doesn't do as good as a 2min Shield wall and last stand.
Now for the idea to allow sword and board to proc. TC would be interesting. Would give us prot warriors a buff to dps some and boast our AoE threat by a reasonable amount. Down side to the TC was that it hits the AoE caps for large packs and doesn't still do as much threat as other aoe classes.
I just hope we don't become a on the move tanking living off SnB procs to keep our AoE threat high which becomes a 2 button spam for packs (if they added it to SnB). The reason i enjoy warrior tanking is because it gets more of my attention then any other class I play.
