Rogues in mixed group

[Warrax]

I'm going to use the same team you commented on this thread (Alliance, so no Shaman) but I do it because I want to main a rogue. Yes, it is going to be way more challenging but I don't think is going to take me that much longer than leveling solo (I'm pretty sure it's going to be faster since I will be grinding on Dungeons).
If you aren't going to main a Rogue it's just going to make your life way harder.

I think the best comp would be Warrior, Shaman(or Priest Alliance) a Warlock (you can send a characetr to a city to sell and re-summon him) and 2 Mages.
3 Mages would be better probablly but I don't think the DPS gain would exceed the utility of Summon, Soulstone and a second tank a Warlock provides.

If you want to utilize all Gear drops you can always have a Balance Druid in the team. But you can also benefit from having an Enchanter and Disenchant all the Leather drops.
