Best toon to counter Royal Guard

Ah AoE damage. I've been running phasma lead with Daka, Leia, QGJ, RG. So the only AoE I've got is phasma's, which just isn't enough most of the time to finish off a toon when the enemy's RG taunts. All the stuns are nice as is all the assists and Leia's multi-attack. But maybe I should replace one of my toons with another AoE toon?
I'm seriously considering just a whole new arena squad right now.
