One would assume so. World of Warcraft, right? :O
Are we playing the same game?
Even if you consider the spells that are instant, you can still interrupt CC chains through the use of your own CC, as well as blanket silences.
That's a fair answer (no sarcasm intended)
The problem however lies in the fact that in my opinion the blanket healing nerf was to much considering the state damage is in.
As it stands currently unless I can cast regrowths into my warlock with full HoTs up I cannot top (and can only just draw even) with 2 melee connecting with him. 2 casters is a different matter, put simply it's much worse! Someone can just instantly die in a deep if I'm CDed on dispel.
What I'm getting at is the pressure is just insane and this has started the whole arms race between damage and healers.
Currently damage is winning simply on the amount of instant CCs in the game.
If I ask santa for one thing it will simply be to remove blanket silence from the game completely (with the exception of priests and Dks). Mages and Warlocks don't need it and it simply promotes horrible game play. 'O missed the CS nvm will just blanket for 4 SECONDS! anyway.' Nothing rewarding or skillful about that style of game play.
Other instant CCs that need to be addressed would be:
Predators Swiftness cyclone (simply far to many procs in it's current format)
PoM Ring of Frost (very easy to fix, simply don't allow PoM to work with ring)
Disorienting Roar (slightly less of an issue than blinding light because of duration)
Blinding Light (Paladins simply did not need this with the addition of Repentance to holy spec)
Blood Fear (10% Hp is not nearly enough of a sacrifice neither is the CD as they can still AoE fear if you go for a kill when you know BF is CDed)
While I'm at it melee have to many CC breakers that need to be looked at (avatar is a great start so my complements on that). It promotes CD stacking and the current state of the game that we see at higher ratings which is to simply force a healer to use his trinket then kill one of the DPS in not a CC chain but normally just 1 full duration CC.
Your game as it stands is very broken (I've played resto druid since TBC and have attained gladiator twice so have some exp). Both damage and the amount of CC needs to be drastically reduced to bring it into line. Certainly this might be hard to do and yes it might upset some people but the way I see it it's the only way to claw back this season.
Of course all of this is nullified if you intended for this season to be played like WoTLK which is 2-3 minute games and people winning on crits and RNG instead of skill?
