5 Shaman.
Everyone drops grounding totems, and then proceeds to NS chain lightning a single target, followed immediately by some shocks for cleaning up.
5 mage > all, pom sheep the whole group, then proceed to buttfuck them one by one.
what happens when the warlock devours someone and the priest pvp trinkets
I: So will that be mostly within one faction, or will that also be two teams coming from different factions against each other?
TC: In this case, you can actually have Alliance teams fighting against Alliance teams and Horde teams fighting against other Horde teams.
1. Warrior
2. Paladin
3. Druid
4. Miscellaneous DPS class
5. Miscellaneous DPS class
Will be the best setup IMO.
I'll be surprised if Blizz doesn't restrict the amount of one class you can have per group. However, there are counters to the all-same-class teams. For example, in the 2v2 arena, two arcane power mages would clean up for the most part, but they would most likely get destroyed by a good rogue/druid team.
A good rogue should never eat a non-PoM sheep. And if they do decide to use PoM on sheep, insignia.Until the rogue pops out of stealth, eats a sheep, and there is no cleanse/dispell.
