One reason why I think players like using the melee weapons more is because they are easier to mod due to Stances, since they increase modding capacity, like Auras do for Warframes. What if we had something similar for primary and secondary weapons? Maybe mods that add unique effects, like a firemode changer (Semi-Auto, Auto, Burst) for most of them, a Vampiric addon for bows/thrown secondaries, a "charged shot" for snipers, or an Shell for shotguns (Slug, Beanbag, Buckshot). If we had something like that, it would make more playstyles for primary and secondary weapons and increase mod capacity, making them a bit easier to mod without sinking a lot of Forma into a weapon. I am also open to more ideas, as I had trouble with coming up with ideas for bows and the throwing secondaries.
