Can I just say that I'm really glad they fixed the issue where the enemies increased in difficulty but your earned exp. decreased? Thank you, Subeta Team! Now I don't feel a loss of motivation as I rebattle the same opponent over and over.

this happened over a year ago...

[edit] I will say it's a good change, but sP rewards still decrease as you get more wins I believe. they also added exp after 10 wins, but it's so negligible that it doesn't matter. 50 exp for an additional win against an impossible challenger isn't worth it, especially when it cost 3k exp for a level, 3.75k for str/def/speed, and 4.5k for hp. I believe this may get adjusted when the next reset happens, but I'm not sure completely.
