Squad Power

I’d worry more about mod farming than anything else. Arena teams should have at least +100 speed on everyone that’s not intentionally trying to be slow (or otherwise compromising speed). The only toon you’ve got with good mods is thrawn. Looks like you’re counting on swapping TM with EP and hoping you stun the enemy team? I guess works against lower level teams, but as you climb the ranks you’re gonna get outsped like a big dog if you don’t farm better mods. All it takes is one toon to be faster than your thrawn and apply tenacity up and you’re toast.
TLDR: get faster mods.
