It's really annoying to get from one city to another when you have already defeated trainers battling you. I'd suggest a little tweak here. Trainers battling you again in a week from their defeat is fine, but wouldn't it be a lot better if you had the choice if you want to battle them or not? Like-... make them ask if you want to battle them or simply make them not walk up to you and start a battle instantly but make the player him/herself walk up to the trainer if he/she desires to have another fight.

It's been suggested many times and we may have a solution in the future, but as of right now the main focus is on making the server more stable. Thanks!
