My experience comes from zealots flamer, enemies that you kill by burning do not have an animation like in vermintide 2, like rolling in the ground or moving trying to put it off. Will those be added on release? because it takes a lot of the immersion and enjoyment out of that weapon, that enemies don’t react to the fire and just fall over dead.
Update: To this date, only infested pox walkers have a burned animation, this is the same for the psykers flamer staff
