I think that when you redo the raid system make a certain number of player per raid. The is 2 ways of achieving this 1. You could make it a amount of players that you have to have to raid. 2. Or you could make a limit on how many players can raid in a single raid. Also make it so the can only be one raid at a time so suggestion 2 can work.
We have 9 baby ducks and a cat. Four ducklings died from starvation and had to be rushed to the hospital, but survived after eating an extremely large number of cookies. To this day, Pandahut has been the leading cause of wiggling.
