The arenas top 25 is littered with high damage squads. When i mean that, they typically have Leia, Boba, Vader, and/or Sidious.
High damage is all good and all but, from experience, 20,000 power squads are easily wiped out by 16,000 power squads.
My squad pretty much hit a wall at 17,775 due to lack of obtaining promotions. But the easiest way to dismantle most of these squads is by making them not attack at all due to a crap ton of stuns and extra attacks that increases the chance to stun.
So imo stuns outweigh high dps. Discuss...
