Nerfing defensive stance WTB EXPLANATION

Their nerfing prot warrior defenesive stance by 5% which in a nut shell is increasing the damage we take by 5% obviously why not increase the damage we do by 5% just to be fair. Not to mention if they wanna screw something up go play around with pallies us warriors finally got the buff we needed and now were getting a nerf FOR NO REASON. Not to mention the fact that prot pallies or pallies in general get buffs i love how there avenger/holy shields damage is increased just because shield of the templar dosnt give it to them anymore.
Deep Wounds: The damage done by this talent no longer receives modifications from effects that increase or decrease damage done by a percentage. The base weapon damage used in the calculation will still be modified by those effects.
I would like to know y you nerfed deep wounds when we have to stack expertise in order to not dodge/parry the target when pally tanks do not need expertise at all yet your buffing their damage and their over all prot tree but we get a stance nerf?
Advice to all warriors go arms cause its the only spec that is getting owned prolly because their gonna just lead us that way until wait warriors got a buff no way new patch equal nerf button for warriors always GO GO BLIZZ you win again,
