Does this include GMs who are gone? lol
I would kill in this order
I would PK from the top to the middle in the order of who I knew I would get away with PKing. Dara is first because he is the least likely to ban me over it. Stratos is in the middle because he can go either way and Peechu scares me sometimes. Erra is in the middle because I'm kinda afraid to PK him, but curious to do so anyways (His avatar kinda freaks me out. Something about that smile....)
The last three I would hesitate PKing because I don't like to pick on people I have not had interactions with. Battledash it at the top, so I think I could not regret it later. (We're facebook buddies. We're cool like that.) Vandala and ebilfish are last because I wouldn't want to chase away any of the newer LC GMs.
