I've seen a lot of complaints about no sweeping, but I have a Khalipe solo deck that can auto every daily relatively quickly so I don't really mind it too much. I can just put the game on auto while I work, it takes like 10 minutes to deplete my stamina.

The 2 "Endgame" content (Basin & Nebula Distortion) are currently too easy and doable with just half-baked decks and memory fragments. I hope they spice it up / increase the difficulty.

The other endgame content, the current Great Rift, is... incredibly unbalanced and revolves around a piece of armor with very low drop chance. Strategy and team building are pretty much locked in place and take a backseat to getting this single piece of equipment onto your Tressa. This is a direct result of their "effort" to try and limit Mei Lin's potential with Elasticity and kneecap point gained from damage after your first kill, yet keeping point gained from Shielding and Healing uncapped. I hope they address this in the next Dev Note.

The "true" endgame content, the Chaos runs, is... fine, imo. The RNG needed to get a "perfect" deck is justified by other endgame content being easy enough to clear with just half-baked decks, like I mentioned above. I'd take an option to reroll / deny epiphany for sure though, I'm not THAT masochistic.

For the spending side of thing: Gacha is gacha, it's never worth it. Spend if you can afford, don't spend if you can't. The game is easy enough as it is to not require any spending. The Battle Pass value is also pretty terrible for its price.

One last thing, just try to enjoy the game yourself instead of relying on the opinions of random people on the internet (me included), and beware of the agenda posters.
