Good points.
Rshams can remove fears, shapeshift to disable slows, ground incoming CC and also interrupt casts from range.
Rdruids can shapeshift roots and slows, shapeshift repentence and polymoprh, knockback and have a ranged silence if glyphed.
Holypalas have a ranged stun/fear, become immune to everything on a 2,5 minute cooldown, aoe-blind, remove roots and slows.
Priests have a feather that boosts speed by 80% for 6 seconds not including slows and that does nothing to roots. NERF IT GOD DAMNIT!
