Yo-Kai Event: BLU Major Griefing Problem

[Myrany]

This wouldn't even solve the issue, you would need to ban BLU from summoning minions to stop people from using it.

CBU3 could rebalance the fates so that they don't die as easily, but it's clearly not a priority for them.
The game simply wasn't designed to account for so many people doing overworld content, so the only thing you can do is try the existing solutions or wait for the crowds to die down.

As I said earlier I used one of the solutions I went to the deadest server on Materia to get my 49 tokens and called the event done there (I didn't want the weapons or mounts). Even during off peek hours for the server I was fighting blues but at least I managed it. It took hours and left me exhausted and angry. Now that solution might work better in a couple weeks but now not so much.

For me though event done I am not grinding out the other stuff for weapons and mounts I don't like and won't ever use.
