Just goes to show that Bungie doesn't base nerfs entirely on the cries of the playerbase. They have thier own data that they look at when tweaking things.

Well... Collecting data is piss easy, specially for a shooter game. It's making sense of the data and then using it to improve or change your product which is the difficult bit. Big 4 companies specialise in this field and charge millions for brand improve. It's not an easy thing to do. You are right that Bungie have their own data and I don't doubt that. I just doubt their skills to make right decisions after analysing the data.
