We already know all the relevant info to calculate the curve ourselves.I'm gonna hold out hope that the level curve isn't as downright stupid as the leaks are implying.
All battles use DP rosters and levels. (Naturally with new moves and other twists.)
The Exp. All functions exactly the same as it has been since Gen 6, but forced like SwSh.
The scaling exp. gains of Gen 5-onward are in, just like they were in SwSh.
In practice, we need to remember how OG DP's curve was like.
