That is not necessary, some people just can't get places we can. We have a guy in our clan who had his hands damaged in Iraq and he has tried literally hundreds of times to get his warlock across the megaman platform puzzle but he can't. So we elected him to just leave fire team, we open the door and wipe when he rejoins so he can be with us while we try to kill the last boss. I hope they never change that part of the raid.
