What lots here fail to realize when saying "fix Traya not Finn" is that STR is not the only area where this is a problem. That same team gets into an infinite loop in arena as well, against any team that isn't Revan. So if they "fix Traya instead of Finn" then every new character they want to be used in arena needs to account for this mechanic.
Also, the change to Finn is likely to just limit the expose bonuses to those that were applied by Resistance allies, which would leave the team functionally unchanged in PvE and in GA/TW.
