In the context of a brand new game (wow classic), if you want to have a mixed team and races, what are the ways you manage this? I have only played Horde.

For discussion purposes (seriously, don't comment on the group comp, lol):
Warrior Tauren
Undead Priest
Orc Shaman
Undead Warlock
Troll Mage

Would you run these to a specific zone?
Would you level these up independently until you can get them all to The Barrens?
