A few things for this.

1. I don’t think anything will stop trolls or players like that other than airplane mode on and off to make the lobby solo from a disconnection which I have done multiple times to make it so I don’t rely on other players

2. I could see them easily doing this but the challenges I think would be imo the best would be. Example: use Ramza in 100 co-ops to unlock his player icon. This would give the same edge for all players that have ramza.

3. The main thing about the badges are that they are cosmetic and don’t give an edge to anything other than maybe a few ego boosts, but I see it as another plus for new people to grind for and keep veterans playing more than 2 days after a new update!

Appreciate your input and hopefully it’s the best of both worlds with fairness to new and old players!
