You might be interested in Dungeon Defenders as some of the characters have powerful crowd control abilities. From Gas Traps of the Huntress to the Monk's Ensnare & Enrage Auras (The Gas Traps act as an AoE Hold while the Ensnare Aura is a huge slow field and the Enrage Aura a big ol' Mass Confusion field), the whole game is based around Crowd Control as it's a Tower Defense/Action RPG hybrid. However, it's more 'passive' control than 'active', as you fire & forget the traps/auras and only maintain them once they're weakened by enemies.
