ret holy power
ele/spriest hard casting heals (while they have passive healing as well)
feint is an energy drain, cloak/vanish stops uptime as well
deterrence stops dmg as well
enhance goes either oom from casting heals or they spend combo points
Contrary to your statement, I'd argue that most dps specs nowadays have some form of a drawback that stops/reduces offensive pressure when using defensive tools in the broadest sense.
You dont understand what sacrificing offensive pressure means. An ele healing is not sacrificing offensive pressure because hes not wasting his capability of being offensive since he doesnt go oom (mana is his resource and healing doesnt make him go oom). He is simply going defensive for a few seconds.
Same goes for ice block/bubble/dispersion. They're not wasting resources, just time.
Feint maybe, but unlike conversion feint doesnt cost that much and gives a fuckton in return. Cloak/vanish no. Just cds, no resource requirements.
Same with deterr, no resource requirement and thus hes just popping a defensive.
Enhance doesnt really heal outside of maelstrom procs and most of them dont care about it anyway, they just #yolo instant blast all the time and maybe crit 150k and kill someone.
Unlike all of this a DK uses his resources to go defensive and thus SACRIFING his capability of being offensive.
A spec equal to that of DKs is destro in the sense that they can use their fel embers for healing and thus - again - sacrificing their capability of doing damage, unlike the other classes.
