Can we agree that because you haven't played Destiny and I have played Destiny that I am in a position to properly judge how much of a problem these exploits are?
They mean nothing. The drop rates in Destiny are shit everywhere. Getting to level 31 will take up maybe 5% of your pkaytime of Destiny if you are trying to earn loot. Nobody cares about people somehow finding some way to get to level 31. It would just mean they skipped some boring time level grinding. It's like figuring out how to skip a stupidly long tutorial part of a video game that everybody hates is mandatory.
The point you keep missing is that exploits/cheats/whatever are inherently wrong, regardless of whether the playerbase thinks they are acceptable or not.
