[Pokemon Reborn E18.4- The Level Cap: a Precautionary Fable]

I think it's a bit of a stretch to say that 100 is reasonable for the canon games. 100 is reasonable for competitive play in the canon games for min/maxing but if you're just playing normally usually there's no point grinding past level 70 as most Pokemon are done learning new moves in their 60s. Plus the fact high level moves were put in the level 1 pool in 6th gen so Pokemon could be taught them early. 

 

Even if you change the multiplier to x3 it's still a crazy amount of grinding that you have to do. Hell, leveling something to even level 80 is time consuming in Reborn. Not to mention I'm not even sure how IVs and Evs would be applied because of how they scale with levels.

Wouldn't raising the level cap be like an artificial implementation of difficulty instead of actual strategy where the "hard" part comes from inflated numbers? At that point, instead of clever planning or counterplay it's kill the thing stronger than you before you get KO'd. Or bring something with a focus slash and destiny bond.

 

That would make it even less engaging than being at stuck level 100. And I don't see feasible way to mitigate the tedious task of grinding to 190 other than adding audino trainers like Insurgence or Spork does.
