Pre BC my 5 man group got steamrolled by 80's. They are not too hard to spot with their 18k+hp. Outlands was the suck as the NPC guards and stuff are like level 57 and wont even agro most of the time so the Horde can just come right into Honor Hold and put the smack down. It wasnt till level 64 before I managed to kill my first level 80 griefer. Now at level 68. I have yet to loose a fight against a lone 80. Two or more is pretty iffy unless I get the drop on them.

The other night I was in Nagrand doing the ring of blood quests. There was an alliance guy there watching me multi-box it and some 80 horde DK flys in and kills him. 12 seconds later and the griefer is dead. At that point I got camped for about an hour by 4 level 80's. I just read a book and hit space bar when the afk flag showed up. I figure its worth it to get 4 people to waste their time. Me killing them is more of an acomplishment than they will get killing a fresh rezed toon 12 levels lower than they are.

Im looking forward to 80. I will be a steam rolling machine. Only a paladin who bubble hearths will survive.
