Trainer teams in PvP

Agree, and it would be nice if they added some increased difficulty levels as well.

I agree that it would be more interesting, but personally I just want the great league battle against Blanche to stay the exact same since that's the fastest way to grind Ace Trainer. Which is much slower than what grinding Ace Trainer used to be in the old gym system.

My guess is that they will change on some schedule, maybe monthly. I can usually take Candela's team with a single Gyarados (unless Infernape drops a Solar Beam on me), so the challenge is pretty much nil.

Yeah, changing daily might be too much to ask for. Changing monthly is too long. Changing weekly would be a big plus.

As long as they dont use the shields or switch you beat them anyway no matter what.

They should better work on that "online" button.
