los snare no son las novas o roots, esos son efectos root
snare es todo lo que te hace slow (Snare - WoWWiki - Your guide to the World of Warcraft)
chill effect tambien son snares pero exclusivamente frost, asi el cone of cold es snare y chill y el crippling es solo un snare pero no chill

y deberia contar con todo esto

Snares include:

Hunter - Frost Trap, Concussive Shot, Wing Clip
Mage - Frost Bolt, Cone of Cold, Improved Blizzard, Slow
Priest- Mind Flay
Rogue- Crippling Poision, Deadly Throw
