I think I posted about it before, but I don't remember the last time I saw anyone use a linear fusion rifle in PvE at least. These weapons just dont have any utility at all, they've proven useless over every single other option available, even precision shots are insignificant on bosses, with a boss perk equipped, they are about as effective as regular fusion rifles; actually, high damage regular fusion rifles are way better. This can be fixed one of 3 ways.
1. Remove them from the game
2. A good damage buff for PvE specifically
3. Make them special weapons instead of heavy.
