I think the pummel change is good. It was silly having warriors be the only tank with a greater than 10 second interrupt.
The Shield Block change is a bit odd. Seems really strong. Basically gives warriors a shield wall in addition to the existing shield wall every 30 seconds. I think warriors have already been in a really good place, so this change confuses me.
I'm not too happy about the spell reflect change. It was one of my primary ways to get rage on Grand Vizier Ertran, for example, and on a 25s cooldown, it won't do that anymore. Still, I imagine this change was to keep warriors from being the obvious choice on Cho'gall.
