sorry but cc is dead for one thing
bring the class not the player
i cannot tell you how many times as a feral druid dps during BC was turned down for MGT on heroic or otherwise because i couldn't CC
even if i pulled the most dps they wanted a mage/lock/rogue
when root got usable inside i was sooo happy we can cc for real!!!!!
cc forces people to bring specific classes. i know it is true that every class pretty much has a type of cc
rogues-sap (most mobs)
mages-sheep- (most mobs)
locks- banish demons/elemantals and fear (not as good as mobs run loose plus can't stop them if they run too far recklessness removed )
priests- mind control- takes mob out of fight but takes caster out too
Shaman- hex
Paladin-repentance (ret only) otherwise none
Warrior-None
Druid- Sleep (beasts/dragons) root (all mobs but most los casters)
Death Knight-None although maybe COI kiting (LOL)
hunter-trap (most mobs) pet offtank (lol but can work)
as you can see not all classes can cc and some are spec dependant
if blizzard gave a cc to every class (screwing pvp in the process) then i would be ok with it. but as for warriors and dks they can only got if they tank and locks are very limited as fear isn't a good way to cc.
