First of all, as far as my DPS capabilities- I do just fine on the damage charts when I am supposed to be utilitezed as a DPS warrior (however, that is rare on my server). Spaming heroic strike, and appling rend is verah nice. MS is a great deal of damage, but there are other ways to get nasty crits and good gear.
I've done some revisions to my concept of this flexible warrior build.
The reason why I had things the way they were was because:
Sweeping Strikes: Pop that off in a crowd of uncontroled CC'ed mobs and smack away with your sunders to build threat once back in defensive stance
Weapon Mastery: How annoying is it to get disarmed in a pull? Uhg!! It can mean life or death in some cases
Curelty: A warrior without at least 10% crit fauils at life.
Pericing Howl: If they can't run fast enough, then they die faster. Also a good bit of threat generated in it, and prevents the runners or lost agroed mobs from running to my squishies.
Last Stand: For the lazy healers out there.
COncussive Blow: Lots of threat, and reallllah nasty in pvp or pve cases.
The unforchant thing about all of this is *I AM* the main tank, and I'm just debating on things. Does one need to be full prot to hold the agro well and or have the surivibility from how the trash or even bosses hit?
I'd like to keep my flexible build for non-heroic five man- it's beastily. But if it's not going to work for heroics and Kara, then might as well bite the bullet and go devasate/anger management.

If it can be gotten away with it, maybe just a sheild-bash spec will do.. Mmm Like this:
