Finally got posting privileges. I should make my first post count, so here goes.
Spammable All-in-one Melee

/equipslot 16 Furious Gladiator's Greatsword
/cast Wing Clip
When a, say a discpriest is trapped and you need to slow him, without getting feared, you can use this to get a wingclip on him before freezing trap ends. Works great against rogues too. Just change the equipslot 16 into a different weapon than you're using so your autoswing refreshes.
Remove deterrence and hop, counterattack
/cancelaura Hand of Protection
I use this even when I'm not specced for counterattack to remove deterr/hop.
Prevent disengaging off dalaran arena edge or bridge in blade's edge. Can't spam it though, or cloak will fail.
/cast Rapid Fire
Simple troll racial + rapid fire for those 1 second cast steadyshots.
