Pokémon Black and White versions

i don't watch the anime and i don't see how it would ruin "flow". i'm not proposing they continuously level up like blarghy113's terrible idea thread for maple but specific trainers, pvp or pvg(ym). it would also help to discourage what i typically do if i die at a gym leader which is run right back in and try again, get experience from the first couple enemies which are usually very easy, die and repeat until beaten. needs more challenge without making them impossibly hard for no reason.

>challenge trainers
>faint everyone at their last pokemon
>recover at pokemon center

aside from losing a lot of money this way how would that plan differ from what you'd like to happen?
