Just figured this out. It's a BWL exploit at "Vaelastrasz the Corrupt".
For the ones of you that havn't been there:
When you aggro him, he throw's a buff on you, that regen 500mana, 20energi
or 20rage per sec, iirc. Now, this is all very good when you fight him,
BUT, there is a exploit to get the buff without aggro'ing him..
The thing is, first you make som guy suicide on him after talking to him.. Go in, rez him..
Then you get a warlocks to place a phaseshifted imp on top
of him. He will then throw the buff.. So if you wipe, and you need to rebuff, just make a warlock run to the other
side, place his imp there, run back to the other side, and let the imp run
through Vaelastrasz the Corrupt, this will give the raid the buff aswell,
without aggroing anything.
And there you go - fast buffing and warriors with full rage when you start
the fight.
