Personally, I find the Reactive Reload/Quick Reaction combo very underwhelming; that's not to say it's useless, but it doesn't really do anything that your standard legendary hand cannon can't. This is especially disappointing when you compare it to the rest of the raid primaries, whose bonuses have a significant advantage in the raid. The auto rifle, Genesis Chain, is great for clearing adds, with firefly and an artificially increased magazine from focused fire. The scout rifle, Chaos Dogma, is in the top-tier for boss DPS, and is easily in the top 3 primaries for this. The pulse rifle, Steel Medulla, is very versatile, effective at doing sustained damage to a boss, and arguable just as good at clearing adds with full auto. The Fever and Remedy offers no such advantages; it wants you to reload, but doesn't help you to do it faster or more efficiently. If you try to take advantage of the Quick Reaction perk as often as you can, reloading after each kill, the buff won't refresh if it's still active. Reactive Reload and Quick Reaction are completely useless during the damage phases of WotM, since all adds are killed when it begins. During the add clearing phases, you're not having to move around that much, making quick reaction unnecessary. If the weapon is intended for clearing adds, I'd like to suggest a new set of perks that I believe would be more useful. The obvious choice for an add clearing weapon is Crowd Control, allowing you to switch between enemies quickly without extra steps to get the bonus. For the perk modifier, kills while crowd control is active would have a chance to refill the magazine (not from reserves). This would allow you to kill the adds efficiently, with very little downtime for reloading. It would still be effective outside the raid, since there's always adds. In PvP, a skilled player might be able to find some use, but I don't believe it would be anywhere close to OP. tl;dr Change Reactive Reload to Crowd Control. Replace Quick Reaction with a perk that has a chance to refill the magazine on a kill, while Crowd Control is active. Fever and Remedy is very underwhelming compared to the other raid primaries and is easily replaceable.
