You know what the main problem is? The fact that this game makes you take a tank into a party comp in the first place. You look at WoW and their successful arena system, you're not forced to 1 tank, 1 healer, 1 ranged, and 1 melee. No, you can do whatever you like. Most will have all dps and 1 healer because tank just doesn't assert a strong enough presence.

Ya'll are saying it too. "WAR ain't OP, it's that other tanks have their 'niche'." Everyone knows WAR acts as a third dps anyways, albeit a nerfed one. There needs to be a removal of restriction on class composition for premades. I'd suggest this freedom to solo-queue too, but only requiring 1 healer.
