This may have already been said as I didn't take the time required to read all of the replies thus far:

Nowhere has it been stated that the idea behind Titan's Grip is to increase your overall DPS. Everyone always assumes that any new addition is purely about greater damage and that it should outshine anything currently available.

THIS IS WRONG! Titan's Grip will do one thing and one thing only: Allow for huge burst damage.

That's right, this ability will allow for incredible, semi-sustained burst-damage compared to what's currently available to warriors (which is already fairly decent).

Burst/Spike dmg is king in PvP and that's what this is about.

its 3am here now and dont got time for to search the posts for what im about to type so if i do im sorry.

i read that the its gonna reduce rage generation but wont it infact increase it? the harder u hit the more u generate. i could be wrong in saying that but when i go fury on my warrior and get 1.6k white crit (in raid) i get what would seem like 30+ rage. so if a 2h hits for 1.6 (rough guess. brain failing at this hour lol) wouldnt it generate the same rage on a melee swing and ALOT more when it crits? feel free to correct me or do the maths behind this. brain is starting to fry now thinking
