Yeah it does throw the strategy away at the Aetheon fight. I was just getting at that, for me, it's kind of fun to take a stab at other the roles. Everyone's got a 50:50 chance of teleporting so we assign three people for relic duty in the final stage of Aetheon. Haven't tried it on hard mode yet, although I was randomly invited to one, and joined as they beat him. Got the sparrow, Mytho, and Vision rifle. That was cool. I plan on trying Hard mode soon though.
