Okay, I didn't really know where to put this but it's sort of a scam so yeah.. If you have a warrior, and want to trade/sell it, get as many HP and stat buffs as you can, if you have Last Stand. Use it and quickly log out.
Now your stats should be great if you check the armory, and I guess this goes for all classes but I thought of this when using Last Stand on my warrior just now.
Not really the greatest "scam" on earth, but it should work on some noobs.
