I'm gonna add my opinion to this debate, and I'm gonna start by saying that's all it is, a debate, as no one has played anywhere near enough of Destiny 2 to really know who is right or wrong. That being said I feel as though you kill your own argument by saying we use a primary weapon most so how do Bungie combat that ? By giving us another primary ! I can see certain weapon types becoming obsolete in the heavy slot and I can't see how that is a good thing. I still think Destiny 2 will be a great game but I have a feeling we will see a return to the weapon format we are more familiar with as time go's by in Destiny 2.
