I might be alone in this, but i agree with Bungie/Luke on the non elemental primaries. Way better now.
Exotics on the other hand, are more then welcome to be primaries. That's what missed in Y1. No one use any exotic primary in pve, not just due to GGhorn, but also because fatebringer was OP, if you needed a long range weapon... VoC.
People used the Fatebringer because it was a really good gun. It being Arc meant very little in nearly every piece of content outside of Arc Burn Nightfalls. If the Fatebringer had been a nonelemental primary from the get go, with all of the other stats the same, it still would have been the best non-exotic hand cannon in the game at the time, and people still would have used it.
Primaries having elements arent the problem. Having an element means nothing outside of 'burned' Nightfalls. I used my Fatebringer constantly... even when I was in a burn other than Arc... because it was just THAT good. Like I said before... if in Year 2, I got an Imago Loop, with Outlaw and Firefly... I would drop my Hawkmoon (which is the only Primary I currently use anyway, so, so much for variety), in an instant, because an Imago Loop with Outlaw and Firefly would be a Year 2 Fatebringer without Arc. (Plox Destiny RNG... drop me my Year 2 Fatebringer...)
The problem with people only using certain weapons was a combination of the fact that there werent many elemental primaries to begin with, and of that very small pool only a few of them were worth using.
By my count, just quickly, off the top of my head... there were 16 possible elemental lengendary primaries in the game during Year 1. 4 from the Vault of Glass, 4 from Crota's End, 4 from the Prison of Elders and 4 from the Trials of Osiris...
Of those 16? 3 of them were S-tier: the Fatebringer, the Vision of Confluence and the Fang of Ir Yut. After that the rest of them were pretty much hot garbage. And if none of them had had elements... the 3 S-tiers... still would have been S-tiers...
So you made a pool of 16 guns, where only 3 of them were any good, and youre blaming the element and not the sample size as the problem? So when Luke Smith says "Having elemental primaries shoehorned people into only using certain weapons and hindered variety" hes wrong. He is actually literally wrong. The actual problem was having TOO FEW elemental primaries and making even fewer of them really really good guns.
To solve the problem, you introduce MORE elemental primaries, by letting every legendary primary in the game roll a random element, just like every other legendary weapon in the game...
I bet right now more people are using the vender bought Hung Jury than there were people using a Fatebringer in Year 1. Why? Because the Hung Jury is pretty much a god tier weapon... I hate scout rifles with a passion and even Im willing to acknowledge that.
