Let's say you were starting over, 5 boxing. You have 5 cute level 1 gnomes, and nothing else. How would you go about it? No SoR/RaF.

Level a mixed team to 85 first?

Level one class x 5, i.e. 5 mages, 5 dk's, etc at a time to 85, then mix & match later?

Get one guy to 85, and just use him to boost 4 others at a time?

Keep all toons on the same server/faction?

Mainly for PvE.
