Hello Ownedcore!
I wanted to share this small exploit I found. If you jump out in the lava at the elite mob in the "Firelands Forgeworks" in Mount Hyjal you will DC and when you log in, you will DC again, and again, and again.. and .. yeah, you get the point.
There is usually a lot of pvp at this area on the highpopulated realms and if you are a boomkin you could have some fun typhooning people out in the lava to be stuck for a long while

If you are a low level you will die by the lava after a couple of logins and dc's but if you log into your friends account and log a 90, he will probably have to contact a gm
