If you get to a point in WOD, were you have no trinket/team cds, then you die. It generally will mean you're being outplayed. To actually stun a target (and it be effective) in WOD is going to be alot harder than current gameplay.
Apposed to what we have in MOP, which is buttons off cd till dead.
Neither can be used in a stun.
D stance is not permanent. You must switch into Battle stance if you wan't any kind of pressure.
If we're caught in battle we have nothing. Trinket into Parry? The most damage reduction we can have is 45%, that's just a normal shield wall to most classes. Not to mention, it's on a 2 minute cooldown. There is 0 rotation of defensive's, we parry incoming damage, then we just afk. It's not fun gameplay to sit in D-stance all game, it's not interesting to either party.
Remove parry's damage reduction. Keep wall, keep the parry element, reduce D stance to 15% damage reduction.
