I think this would be cool for an area. Basically there is a war area and the player needs to level up a lot before entering this area. It would be less frustrating then. There is a war between monsters and juiceans. Maybe there could even be a place where you "sign up" for the war, and if the player is on a very low level, the people could be like: "SORRY KID, YOU CAN'T JOIN THE WAR." or something. However people might find this idea offensive. Obviously the war wouldn't be more serious than the rest of the game, but if you don't like this idea then that's fine.
