After playing since the xbox launch and having played alot of vermintide 1 and 2 the features I miss the most from those games are:
-end of match score board
-having bots be your alternate charchters so you can spec and level them to be useful
-red weapons as end game loot
-being able to test your weapons without having to go through a loading screen
Also QOL features from other games or pc mods that would be good are:
-being able to enable damage numbers and health bars in matches, not just in the testing area
-full button remapping
-being able to see performance information, frames and ping
