Listen I agree with you. Ghorn is not neede like it is advertised. However if you have a team of 4-5 and only need 1-2 more, knowing there are randoms and may cause the team to wipe, it is a little safer knowing they might be able to hold there own. It's the same reason that everyone only took random warlocks back in the day that vog was the only raid. The thought that well if they suck at least they can self res and try again. It's a pure safety net. But I do agree if people keep demanding it (which I think they will even more now) bungie will just keep nerfing instead of makin new gun or buffing current one to rival the ghorn. All in all its a bad situation.
