I had somebody go the extra step and say hunters are useless in PvE and are only good for PvP. In the raid specifically their golden gun can be useful in a pinch to take out oracles. I'm sure the blade dancer can be useful when defending the confluxes. I don't play as a hunter, but I know a few people that do and they are great. I guess that the guys with you are right, when it comes to pushing Atheon off they are useless, but that doesn't encompass the entire raid now does it?
