It's not so much the "new" weapons as the weapon balances (Destiny)

They made TTK much faster since initial launch for all pulse rifles and hand cannons. Increased range on most shotguns. Un-nerfed Mythoclast (which is absurdly good now). Plus the game has been out for so long now that basically everyone has these weapons. But that's not what I'm discussing (though I do think current TTKs are too fast).

With all weapons upgradeable to the new max level, everyone still has these awesome weapons when it comes to Iron Banner. If Bungie wants me to use any different weapons, they need those weapons to be better in some way. For PvP purposes, TTK is pretty much the be-all, end-all stat. Want me to use the new weapons? Want people who don't own the expansion pack to buy it? Give them something they can't get anywhere else... Better guns and armor. Which, I'm afeared, means weapons with even faster TTK.
