Rotation feels really flat now. I am not sure if this is going to be a buff. I think it will either make no changes for good players or even be a nerf. I really like the way you can stack tfb and release it within a CS window for huge damage. Most people, especially non warrior players, dont know this, but arms is really complex if you want to "master" it right now and you can do so much to improve your dps (although is just a little gain). But after the patch I think worse players can pull nearly the exact same dps as good arms players.
What bugs me most is that you just cant get everything released in just 1 CS window. There is no reason to pool 120 rage into a CS window with 5.2. If they would increase the debuff from CS by 2-3 seconds it would be great.
