All mage leveling group?

[EQBallzz]

So we had a small guild group leveling last night in Crystal Caverns and started talking about potentially leveling some new characters and what they might be. We ended up deciding to try an all gnome mage group for fun (3 of us) and potentially will add a 4th or 5th to the group.

I have anecdotal evidence that two mages can do pretty well in a duo but I have never played a mage myself. How viable would an all mage group of 3-5 people be for leveling and dungeons? It doesn't have to be optimal and I'm sure there would be risk or downside to not having traditional roles but the challenge sounds fun (or maybe it will be faceroll easy I don't know).

Anyone have any thoughts or experiences with such a group?
