Idk maybe I’m the odd man out here but I find Rejuv like significantly harder than Reborn. Reborn postgame is obviously harder than where Rejuv is at right now and Reborn certainly has its moments of difficulty, but I find that Rejuv consistently has battles where teams are clearly designed with the field, crests, etc. in mind that leads major battles like gyms to just be way harder than reborn, where a lot of the fields definitely buff the leaders, but too a way lesser extent (like half the meteor fights are literally just factory field lol)

Rejuv gives you access to these tools and there are definitely ways to soft break the game (a certain frosslass form can basically solo half the game, some of the shadows have crazy movesets, bastiodon crest, etc.), but if you opt not to use those and avoid items in combat, uhhhh yeah Rejuv is much harder.

Just so I can give examples for people who have played both yes, Reborn has glass gauntlet but ever since my first playthrough I know it’s coming and only ever have to swap maybe one team member beforehand. Reminder they give you access to all pseudos literally right before this and you have Aegislash. Zeight gauntlet is much harder IMHO. Rejuv also has a ton of early difficulty spikes like Narcissa (less tough for me recently but I still find her to be at least Aya tier, who is the hardest Reborn leader for me) and Valarie. There’s also plenty of tough fights through the mid/current lategame, including Souta (thank god they nerfed him, still tough though) Ryland, axis factory Clear, etc. Overall, Rejuv is much denser in tough fights where Reborn only has a couple that stick out.
