Future weapons and things that should be in the game from the start

I’d like to see a weapon combinations that are very often used and portraied in Warhammer 40,000 universe.
Chainsword and a Laspistol/Autopistol for example.
To be honest I was kind of expecting this to be a thing in this game from the get go since Vermintide had this feature.
I also hope we could see a meltagun implemented.
I don’t think ‘‘combi’’ weapons should be a thing in this game because it would make other weapons kinda irrelevant.

Melta was in the insignia leak, so it should in theory come sooner than later.

As for Sword and Pistol, they might get introduced with the Squad Leader or something, they still will release weapon in the future, keeping some more simple ones to pad them out, also it might not appear in the same simple way as the Rapier does in VT2

As it would most likely have ranged ammo to balance the stronger ranged capacities, so either it would be in the ranged slot (Like the Grenadier Gauntlet) or it would be a melee weapon with a new system that they haven’t shown yet

Idealy it should be a melee weapon, with 2 different weapon (Chain and Normal) but each with a few pattern making it the Rev, Laspistol and Bolt pistol

Combi weapon might happen in some sort, with the special attack being the other weapon (Like Shotgun with Flame canisters)

I am hoping for any held back content tbh. Fatshark has been dead silent lately.
