I, for one, am very pleased with the changes, Length, rewards, challenge level, accessibility all feel very much worth the effort, and appropriate to the task at hand.
For this one, I say Kudos to the team!
(One small improvement I would like to see regarding feat completion, if the “gear gate” is permanently gone - the undersized and mono-faction rewards should no longer be exclusive. As an example, with this current Challenge, if I were to complete Tier 7 with Rey, C3P0, R2D2, and BB-8, it should award all 3 feats - all members of the team are tagged Resistance, I have completed it short handed with 4 characters, and I had 3 light side Droid tagged characters. While not a huge deal, it just seems strange that if I can do it with 4 members of the faction, I now have to do it again with 5 members of the faction.)
