I want to see utility weapons in 7 days to die. Weapons that are more for a tactical approach. I've been watching videos about Immersive Sims like Deus Ex and I think that type of gameplay can be brought to 7dtd.
Here are some ideas that I had rattling in my head.
Caltrops temporary spike traps that you throw down. hurts and slows enemies
Grappling Hook
Riot Pepper Spay
Smoke/ Poison Bomb Slingshot
Sticky Mine Grenade Launcher like in TF2
Stake Electric Tether making a line of electricity across the 2 stakes that you shoot out.
some you can use in horde scenarios too.
