I’ve never had a problem with my Ele, I’m lvl 60 atm and currently specced full fire with 10 points in Air and Arcana. I did start off using a staff but I began to feel it was too situational, especially the meteor shower. I changed to Scepter/Dagger which I now think I’ll stick with. Anyway, if you just do a little hopping between Fire and Air when you run out of things to cast, make sure you have Arcane Power, Wave and Blast and I guarantee you’ll be able to take on 8-10 mobs at a time.
