It makes all the difference.
If your team did have Ghorn for Atheon. You would have beaten him in one tele in >20 seconds.
There's a video on YouTube.

You can beat Atheon in one teleport without g-horn. Fight him with all level 32/31's. IB with hunger of crota or any machine gun works just fine

One teleport or two teleports.. I got enough time. I just want to say, you don't need a ghorn. I prefer to use exotic primarys like thorn, tlw or suros.

True, I'm not saying that it's hard. I'm just backing up the OP's point. It would be that much easier.
