Anyone who knows anything about caster PvP knows how reliant Mage and Warlock were on blanket CS to do any pressure. Removing it was a stupid change to begin with and meant that all Melee/Caster/Healer or Caster/Caster/Healer comps had to have a Spriest for the blanket.
The Cyclone DR change also ruined nearly all Rdruid synergy with everything except Warlocks and Spriests (forcing you into either WLD, RLD, etc). The cyclone change from 30s to 20s is a good change for Ferals, meaning that it'll be used either defensively or offensively. Not both, but is still a reliable CC.
