I'm personally more of a fan of this, I don't think a player should be punished for leveling a pokemon to 100 personally, if they put in the work and a pokemon meets the requirement for evolution, I feel like they should be able to have that option somehow.
I can respect amanu, he whispered me once saying he respected my choice to use dewgong over walrein or something along those lines back in 3v3 days. Good guy
