I really enjoy using campaign variant weapons that you can get from the vaults on BTB Fragmentation map and BTB Fiesta mode was really enjoyable for the Yappening event. So I thought, assuming the default weapon also was added later, what REQ weapon(s) would be something you personally would like to see return?
For me, I liked the Ad Victoriam and The Answer. I liked firing the Ad Victoriam up high and then target and enemy and have the rocket come down like a Javelin missile to avoid obstacles.
