Below list [u]balanced[/u], simple ideas for any exotics that may need adjustments. These include weapons and armor. Add ideas and the reasons why and i will add the best ideas.
Dregs promise- restore previous damage.
After the decrease in both its fire rate and damage this weapon lacks the consistency to get kills in a timely manner. You can reward players with good accuracy by buffing the damage alone, which will increase the kill times.
Fabian Strategy- add 10 to the mag, 2 feet in range for activating the perk that changes its archetype.
Having 2 archetypes in 1 weapon hinders the weapon. It has neither the magazine size of a high rof and because of the perk it changes damage at a nonoptimal range, during which most players can easily counter it.
Celestial Nighthawk- 2 shots worth 3 shots each.
Great overall but has no versatility when dealing with mobs or in pvp. This allows players counter supers like ward of dawn with 1 shot and still have 1 remaining. Also able to kill multiple high level enemies in pve.
