Nah. We start the Double Trouble quest, go to the nest each player in a different corner. Once everybody is ready and there is no boss in the area, we start. The objective is to knock the other player down from the nest to the area below (5 is it?). If Rathian and Rathalos appear, then that just makes it harder to drop the enemy.
This is a "we are really bored" type of game, but hey, it works haha. I've seen it done with Jho too, so we can choose. The players that were eliminated by being thrown off go fight the monsters, we do want to finish the quest if possible
