The weapon itself used to be one of my favorites especially for d1, not really used at all from what I am aware of. Just my personal opinion on it is swap it to the energy slot, there is only one linear fusion that is used outside of this and it happens to be a kinetic slot. I just really look at it from a variety end.

Queensbreaker is forgettable and not needed, but there is still Sleeper and Line in the Sand if you managed to get it a few seasons ago. I think it will be set so unless there is a new one coming we won't have any in the new season.
