Titan's Grip, in case there are any of you in the audience who are not familiar with it, is the Fury Warrior 51-point talent. It allows the warrior to wield two 2-handed weapons (or a 2h and a shield, I guess, if they wanted to). Pretty awesome, right? Yes. But as a counterbalance, to make sure Fury isn't doing overly insane DPS, it imposes a penalty in the form of a decreased chance to hit with "damage-dealing abilities that require a weapon" (i.e. most special attacks). That decrease started out at 15%, and was changed to 12% before 3.0.2 went live. Ghostcrawler has now announced that they're changing it again, to only 5% decreased chance to hit with special attacks.
This is a massive buff. Part of it is in response to raising raid boss armor by 10%, but this goes well beyond correcting for that. GC says that this probably makes TG a bit overpowered for a 51-pointer. I have, though, seen many, many Warriors complaining about the huge miss chance when the talent is picked up, so hopefully those complaints will be put to rest now. Oh, and the attack power coefficient of Bloodthirst is up too, from 45% to 50% (i.e. it will scale better as you get more AP). But man, TG is going to be crazy good now.
