My Pally plus 4x Shammy group still has the peculiarity of having idiots try to gank me (they are solo). I think they think I'm a bot? or maybe that their screen is messed up (since my shammies are all same name with different 'a' - hard to tell when they are standing on top of each other).

At level 80 it only gets interesting when they start calling in friends and soon I have 20 people camping me :)

Thats when I move to my second team and level for awhile..

I had the same problem while levelling but it seemed to come in bursts and honestly... I wasn't really ganked anymore while levelling my team than I was while levelling my solo characters. It just seemed more frustrating for me with the team.

I say wait until you are out of Hellfire before you throw those 60 levels away. I think you will have it with whatever group you have, but my next group will be droods.
