2 things. 1. What console are you on ? 2. Killing Skolas isn't that hard. My friend doesn't have a ghorn and his friends didn't use it and they killed him. It requires teamwork yes like trials but trials is competitive and requires skill and needs teamwork like I said. I know about the cheating and I know it's a problem but bungie is working on it. The worst cheaters get console ban. The ones that do basic cheating isn't bad as the console ban though. These who achieve these requirements are lucky but as of now you will have to accept the fact that this is happening.
