DE I believe already stated that there would be more to come, so which weapons see the least use and are likely candidates? While on the topic of weapons as well, what do you think possible infested lich weapons could be? (As in existing infested weapons turned into the infested version of kuva or tenet?)
Unfortunately, Buzlok is not really a candidate because its alt-fire is already occupied by the tracking dart. Unless they change the incarnon activation method.
