after scanning through the thread, i was pretty appalled at how uninformed and/or unintelligent some of the responses are. so, if you dont know why im asking what im asking, please take a look at the recent dev blog before reading anything else here:
no, blizzard isnt nerfing cc. theyre buffing our skills, some of the ones we dont use because they suck in inferno. however, i differentiate between "hard cc" and "soft cc" rather than "cc" and "snares" because my definition comes from my league of legends experience rather than ... what, wow or wc3 probably? so reading the dev blog, i automatically assumed slows were cc as well, but that isnt the case at blizzard. (but whether well get buffs to slows is still up in the air... please do!)
as for caltrops: torturous ground... well i hope lylirra or another blue peeks at the thread again to clarify if the immobilize will be subject to diminishing returns! id suspect it will.
more specifically, blizzard totally forgot about a situation... everything in the blog is about stuns.
a soloing ____ is using a cold weapon follower (or cold stone of jordan). followers always aggro on mobs before you (which is a problem in itself), so it starts autoattacking the next closest mob, applying the soft cc.
what happens when the player uses a hard cc? is it reduced?
soft cc isnt very useful to melee classes (situational), but hard cc is almost always invaluable. would a barbs ground stomp stun length get cut by 30% because his enchantress is overly willing to start a permaslow rotation and he doesnt choose to keep his only gap closer in his skill set?
will the caltrops: torturous ground kiting dh's get the full effect of the root (another hard cc) if they run a cold bow scoundrel? will any cold wielding follower screw over frost novas? horrify? blind (since d3's version of blind amounts to a stun)?
edit: thanks lylirra!
