The only thing that changed is that healers started being.huge douchebags and hug pillars even more, and together with healing being shifted to instants, they were almost never in the open.
So since MoP, the meta is instant CC into casted CC because unlike before, there's no way to land a CC on a healer unless he's stupid as fuck. Warlocks and Mages excelled at that in MoP, Mages excel at it in WoD, hence lock shaman tears.
The only reason why CC got easier to land is because healers became ridiculous with all the instants and shit they have, so now we have mechanics to land a CC 100% ( Mages with deep and dual schools, priests eith feathers and guise, hunters with binding explo freezing combo, etc )
Stop whining already about CC. Any sane person would take a loss due to CC over a loss due to CHOO CHOO IM BLIZO MOTHERFUCKER I PLAY THIS FUCKING FAGGOT THING AND IM SO FUCKING GOOD AT IT RESPECT MY MORTAL STRIKE AND MASS SPELL REFLECTION AND MY ENH SHAMAN SIDEKICK U PIECE OF SHIT SHADOWPRIEST
