New favorite thread. I love these lesser known tips and tricks.
Not nearly as good as they used to be since they take up a guardian or battle elixir slot, but the various forms of Juju are kinda cool.
Juju Flurry - Item - World of Warcraft is an interesting one. 30 haste for 20 seconds with 1 minute CD (although the spell itself says 10 second CD, may have to test this tonight).
I'm sure I'll come up with some better ones after a little brainstorming while bored at work.
