Just hit 80 today and was able to roll out my new team to arena:
Rex (L) - [G10]
Fives - [G9]
Kit Fisto - [G9]
Aayla - [G10]
Leia - [G9]
over 37k power and fun to play. the potency up from Kit allows Aayla's stun and "Fives" speed down to hit more frequently and the counter/assist ratio has been very nice (probably some lucky RNG).
NOT having to hide behind a tank (that taunts) is so nice. It is very liberating from the current meta.
post your NEW 80 TEAMS or even a fun team you would like to roll out in arena.
