I currently do not see the value this game gets from this "feature". People dont want to wait to evolve their pokemon, atleast not too long - they are given the choice of doing the story with an unevolved pokemon or train them until about level 95 (on level 36-39 pokemon) and then evolve them. Why?
The official Pokemon does not limit you like that. There might be moves which only an unevolved pokemon can learn, but thats it - no increased experience requirements after evolving.
If i just dont see the reasoning, explain me please :)
