As it stands, Co-Op is a part of the grind. It serves a purpose, and I play it for that purpose. However, PLAYING this game is actually FUN at times, and I wish I could have more of that experience.
-More bosses in Co-Op would be fun. Throw in Alpha and Roland, all the Pain Cage enemies.
-Allow Uniframes/Transcendants to participate in Co-Op. Even with the drawbacks they suffer in normal team compositions, doesn't matter. They already deserve more love as it is.
-Different Co-Operative modes would definitely encourage more social play in the game. Beat-em-up or mob smashing modes like some of the story missions, getting to explore larger maps together with friends.
-Existing Co-Op bosses could use a significant rework. Rosetta is fun to fight, but Osiris and Sister are both a snoozefest. (Sister not as much.)
Furthermore, in relation to some of these changes made "for fun", which may or may not throw off Kuro's idea of balance and/or progression, using any of these other features could be considered "extra" and disable rewards.
-Co-Op should not cost Stamina when Scavenger tokens are empty; allowing friends to play together without worrying about resources.
See @smoky halo's suggestion (https://discord.com/channels/595893569609269251/1071778032848752712) for other Co-Op game modes, which I agree with and expands better upon my suggestion. Tack on more suggestions if you have other ideas, too!
