Slug Shotguns, High Impact Pulse Rifles and Bows getting varying buffs next season. Nearly all of which are getting sunset the following season...
Unless some new ones are getting added between now and then of course. Otherwise "underused" will become "unused" and these changes will be pointless.
Same goes for Aggressive Frame Pulse Rifles, and I imagine a number of other weapon archetypes. All of which will soon leave a void behind because there will no longer be any light-viable weapons in those archetypes.
