That's just the way I've always run my RPs, when you catch a wild pokemon the pokemon that battled it does not gain any levels, much like in the game. That's why I leave the decsion up to you guys on the routes weather you catch a wild pokemon or battle a random trainer for experience.
And alright cool I'll update the profile page on Sunday when I get back to my apartment, it'd be to much of a hassle to do it from my phone lol.
