Great points.
The only reason why three Pokemon were allowed, was because when you go back to the station, your Zone was over.
As for the Pokeballs, well that can be modified, but the carrying of a whole team of Pokemon in the Zone feels a little overwhelming-especially against Legends, although we did instate that one at a time rule, but then having 6 to swap from is well...lopsided. :O
Will run this by the other half in a few days
