Thanks, Cyclone. Appreciate the tip. I'm in a bit of a bind at the moment. My only other arena viable characters are Daka (71, 7*, Gear VIII) and ST Han (71, 7*, Gear VII with one slot for VIII). Either of those could be interesting in the lineup -- thoughts? (I have a few other 7* level 70+ (e.g., Mace, JC, Barriss, Phasma), but I do not consider any of them viable in the current meta and Phasma is underwhelming if not leader IMO.)
Working on Rey and JK Anakin, but neither are ready at the moment. Unfortunately, RG, GS and Dooku seem like they would be the best fit, but they are a long way from being arena ready.
