The emotions are already in game ( you can see it in main menu and game trailer ), but except those we need smtf to celebrate victory or show our expression. What can i say about chat wheel, well it just useful( especially if commands will be voiced).
To be able to shout more things than when you ping something like “healing here!” would be great. In Vermintide 1 there was a mod that allowed you to play your character voice lines at will (but it was quite complicated).
A weel or binds to trigger voicelines for:
Healing/heal yourself/I need healing
Go go go!
That would be a great thing.
With a bit of luck the mod gets redone in Vermintide 2 and sanctioned.
