Too hard to catch regional Pokémon

I love this game a lot but I dont like the fact about regional Pokémon. Take Mr Mime for example. Hes only in Europe or something and I want to catch every Pokémon in the game but I cant travel to where Mr Mime is at! Please delete the regional Pokémon thing its just getting on my nerves a bit :)
