To be honest I bet this won't work let's say they make it everyone gets enmity. Everyone does the normal speed run and runs to boss, healer closely follows tank and as soon as he is about to die hits swiftcast raise. Now everyone dies like normal and mobs will run back at a guess. PLD nows accepts raise and raises the rest of the party. They need to make it so you have to kill all mobs to open boss gate!
