This opinion probably isn't shared by everyone, but I have to say: I miss crowd control in PvE. Nowadays, thanks to Death Knights or Blizzard or whoever you want to blame, instance runs are more or less zerg affairs -- everyone runs in on a cue, targets whatever the most dangerous mob is, and then lets the rest die off from the incidental damage thanks to their glyph-ed up, AoE abilities. But I long for a more civilized time when CC was used as a more elegant weapon, when a successful group was based on teamwork rather than gear, and when you needed a sheep, or a trap, or a banish, or all three, to make it through the instance.
Fortunately, crowd control isn't dead forever -- GC confirms that while Blizzard doesn't want every pull to take "months of planning" (and obviously they want you to bring the player, not the class, so requiring a Warlock or a Mage along isn't always the best policy), "there will be more CC in the future." Of course, whether that means raids only or future expansions, we have no idea. He does say that "Noxromulous" was made to be accessible, so you might think raids, but one instance players always mention in terms of 5-man difficulty is Magister's Terrace, and let's not forget that that one also came in a content patch.
Despite the bad rep that CC has gotten in PvP, it plays a significant role in the strategy of PvE, and lots of that interesting gameplay has really been lost lately. Hopefully in the future, we'll see Blizzard able to bring back sheep and traps in a way that will test groups without leaving anyone out.
