Galactic Challenges - feedback on scaling difficulty, and broken rewards

Tier 6 is all you need to beat with the appropriate faction in order to get T9 crate, so as someone who has to occasionally settle for that one, I'm pretty content with it being easy enough to beat without relic toons.

Yes, tier7 is huge jump, but it's basically irrelevant because if you're not beating the higher tiers, you're not even in contention for top crate anyway. I've always assumed this was by design.
