From the top of my head:
Warrior - nothing
Guardian - Interventions (to ally, soj, or enemy)
Revenant - Shiro util, GS, maybe more
Ranger - nothing?
Thief - sh5, shadow step, a portal for allies, steal, various weapon skills, maybe more...
Engineer - shift signet
Necromancer - wurm, spectral walk (backward), scourge portal, pulling downed players
Elementalist - blink
Mesmer - blink, portals, some weapon skills maybe.
This list is probably incomplete.
