I know this is going to sound silly but I really miss the 12 days of Christmas event from the original Vermintide game.
That feeling when logging in to open Christmas presents and getting fat loots.
It would be a perfect time to bring back some of the wonderful things from V1:
-Red outfits (for first 5 careers)
-Hats that haven’t made their return to V2 yet
-Unique weapon illusions (like Sienna’s skeleton staves)
Or of course, give out some items that will help new players along like one random red item or some red dust. I was very thankful in V1 when I got my awesome orange dodge trinket from the Christmas event! I felt like the last person on Earth who didn’t have it.
