Maybe additional respawn points closer to the end or a way to transport from the start to the end after all the shields are down.
I've seen this happen a few times now and that is that during the final battle people get disconnected. We remain on the map as long as possible but usually when they get back on it is already too late, because they can't run from the start of the map to the end of the map to pick up their drop in time before they are thrown out.
That or some way that those left can click on the drop and get a menu where it said: Mail items to: Name@Handle
There the one who lost connection's name and handle would be the only one to appear.
If not one of these solutions then some other solution that would prevent this from happening.
