Fun premise but if someone asks what not to do for game balancing, look at pokemon go's raid system. The only ones worth going to are too difficult for a single player so you either have to wait for 5 other people to just happen to raid at the same time as you or wait until the bourgeoisie company decides to give the peasants a free remote raid pass, or of course pay to get a couple. Not to mention actually trying to catch bosses, god help you if you're a new player without 50 golden berries
