I did this tonight with an ops group of 6 people. Only 3 need the MGGS or w/e it's called. Activate the bridge and whatnot, then have 5 people go to panels A, B, C, D (needs grapple), and E (needs grapple). Have the one at E be a sage, if possible. The sixth (definitely a sage in this strategy. This person needs the MGGS) should grapple to 3, then 5. Sage at E grapples to 3. Sage at 3 "rescues" people. Sage at 5 rescues those at 3. We were lucky enough to get to point 1 within 2 minutes. All in all, it took us about an hour since the grapplers kept dying due to bugs. Hope this helps!
