This is not good for melee classes but its good for casters and hunters.
To do this you need:
WoW Emu Hacker for 2.3x
A spellcaster or hunter.
A bow or a wand.
And if neccesary a healer.

Its recommended to be 2 on this, if you got a friend that heals you. But you can solo it.
How to do this: Go into a heroic or normal. Find a boss you want to solo. Put on fly mode and speed hack, like mac 10 or griffin. Depends of how much space you got to do this. Like in ramparts, you find Omor the Unscarred. There it is much space and you can easily solo him. Now lets continue.
Aggro the boss with a wand cast or something. My friend found this when he was shooting with hes wand, that you can move and shoot. That might be fixed on a few servers.
Now when you aggro the boss you just flying around him in circles and shooting with wands. He will be unable to catch you exept he shooting magic. It might take a while to kill the boss but it is very useful if you need gear or something.
You can farm badges with this, gear with this. Gold with this.
