It doesn't look like everybody's too happy with the new changes being made to World of Warcraft's warriors for patch 2.3.

As Raze over at the WoW forums stated, Blizzard may want to reconsider their revamps to the Tactical Mastery skill under the warrior's protection talent tree, which will boost the threat generated by the Mortal Strike and Bloodthirst skills while in Defensive Stance. Before this, the skill just allows players to carry over some of their Rage points as they switched stances.

While the the changes were a big advantage to prot warriors (normally your ideal tank) Raze's point was that it was all the more needed for warriors specializing under the Fury and Arms talent trees. As the player elaborated:

Include this talent yes, but put it in with either Improved Heroic Strike or Improved Thunder Clap instead. These are tanking related and can be picked up without having to put points in prot and gimping ourselves.

I look at it like this: we took a talent that was very desirable to Fury and Arms warriors, but not quite desirable enough for them to take, made it more desirable and gave it a reason to be in the Protection tree.

Stance dancing always has been important to PvE and will become more so for Alliance players with the change to Fear Ward so while the talent is very useful in PvP I think it's wrong to call it a PvP talent per se.

Bear in mind though that none of these changes are set in stone and we will want to see how everything pans out on the PTR before any changes go live, but personally, I think it would be nice to see a bit more experimentation and variety in PvP builds.
