I have a feeling it was. Not to blow my own horn, because others also posted the same thing before me here, but I posted here about having killcams off by default, and having to press X or something for death and Josh himself quoted it and said that it could be a good compromise and something they were looking at based on beta feedback. Others probably also mentioned it on other forums and soon after, they announced killcams off by default and that you could press a button to view how you died if you wanted. Not saying guys like me are the reason, but it does help when devs acknowledge good ideas, good criticism and feedback.
The outcry over the loss of the SPNKr, here, on Beyond, Reddit and Waypoint absolutely had to do with it coming back as a legendary weapon. Why only the rocket announced like that in the after beta post? It's because quite a lot of people wanted it back, wanted it as legendary weapon as a compromise. That's why two way conversation is important, because development doesn't exist in a vacuum. Not saying they should cater to what nerds say on a forum, but if you actively engage and read what they write, you may incorporate some suggestions.

I mean most people here, on r/Halo, and Beyond complained about DMR scope and bam, it's changed to suit more or less the older zoom style.
