I have a retired pve group from a few years ago. 70 paladin, 66 mage, warlock, priest, shaman. I'm happy 2-3 boxing for now with new characters and my paladin as a booster, but reading some of the posts here got me thinking.

1. I see some of the 5-box groups here are crushing heroics in 15-30 minutes? Damn! Would a mixed group like mine be able to do that at 80, that fast? Or would it be more like an hour+ each instance?

2. How many hours/days would you guess it'd take for them all to get to 80? PvE server.

3. Would this group be fine in Cata? Or who would you sub?

I'd post this in the group composition forum, but I don't have access yet. Kinda itching to know this stuff now. Thanks!
