Warden: Movement Restrict (Root), Banish (Root + Stun), Entangle (Root + Stun... from SotO)
Scout: Lasso (Root), Throat Stab (under Silence, but more of an Interrupt)
Mage: Lightning (Root), Discharge (Stun), Static Field (Root + Stun), Silence (duh)
Those from the 3 classes I have... I'll let others fill in the others. Also, if we include some elites, should be a few more added...
Mage/Scout: Thunderclap (Root)
Scout/Mage: Ignite + Prairie Fire (Chance of Root)
Scout/Warden: Briar Shield + Deep Roots (Chance of Root)
