Things like this confuse me; it makes me pretty sure people don't actually play a warrior. The only thing "skillful" about shield requirements are making macros; the rest is just annoying as hell doing 10% of your normal damage while its up. Plus the delay, I suppose you could say it was skillful to account for the delay in the macro to spell reflect but jesus you're just reaching if thats the case.
Stance dancing is even more important now than before. The "skillful" stance dancing pre-mop was making macros to use your stance required abilities then switching right back. Now stances are like they should be; battle stance gives us more rage which we need more than ever to do damage, and defensive stance keeps us alive. Jumping between the 2 constantly is what good warriors will do; I find myself stance dancing more often now than anytime this expac.
edit: What they need to do to warriors is a few simple things:
Def stance reduces damage by 20% down from 25%
Intervene no longer breaks roots, all warriors get a new ability that serves as a rootbreak that costs a small amount of rage on a 1 minute cd.
Nerf deep wounds by 10%, buff mastery to 75% weapon damage.
Their toolkit is what it needs to be, they just need minor tweaking imo.
