Currently the grind to level multiple characters to 30 is significant, and is compounded by the need to acquire materials and currency from scratch.
In Vermintide 2 levelling new characters was more interesting due to most weapon archetypes being unique to each character, and shared resources helping you obtain new items.
In Darktide starting a new character isn’t as rewarding due to the humans sharing most of their kit.
This would be mitigated somewhat by having crafting materials and currency be account wide. Possibly weapons too, although this could be less viable if it disadvantages the Ogryn’s progression.
