I thunderstorm and drop earthbind totem then move to the screen of the one being beat on and hit my follow - everyone turns to the new leader and I blast them before they can get back to me or chase them down. As suprafro said, you want to set your keys up so you are only casting one Thunderstorm and another toon is dropping one earthbind - not all 4 at once.

I'm 64 now and every now and again a 70 rogue manages to pull me apart over 5 or 10 minutes but I do not fall victim to 64 or 65 rogues (maybe one toon before I kill them). Nothing else my level gives me any trouble.
