well mages would be the only ones currently that I think would have any luck in 2s. With pom -pyro,arcane barrage x2 you could blow up anyone who didnt have an immune abilty right away.


Edit; after thinking about it. ATM (expecting arcane to get nerfed) if you went invisible and popped out and then pompyro-AB with both you could surprise before they popped their immune defense.
