class race combinations that have great synergy or are IMBA

[JackBurton]

what class race combos are imba?

like for example
a tauran pally can chain/stun AE CC using war stomp and cast stun
a mage goblin can escape using blink and rocket jump twice right?
a goblin DK can jump and grab someone

what are the others?

Worgen Druids have the most possible speed boosts (2 of which remove roots/snares, and 1 of which can remove all roots/snares for your whole team):

Stampeding Roar
Dash
Darkflight
Cat Form passive speed boost

[JackBurton]

another great CC combo i forgot is
Tauren Frost Death Knight
K Hungering Cold 1 min cooldown and 10 second CC/interupt
Warstomp stun/interupt up to 5 mobs for 2 seconds

both of these placed in a smart round robin are pretty nice.
