Okay, I’m gonna come at this from the perspective of a Mercy main.
To answer your question, put simply: No, Mercy doesn’t need a rework.
That being said, however, her kit is definitely in need of a refresh, of some description. Mercy is one of the oldest heroes in the game, being in the game since OW1 launched. 6 years is a damn long time, and with Mercy’s kit, it shows more clearly than any of the original cast.
With Mercy, there’s only really two outcomes of a match: Mercy’s incredible survivability enables her to have a near deathless match, giving her unrivaled reliability. Or she feeds. As easy as it can be for good Mercy players to excel with her kit, they can just as easily flop, and then her kit gives her team nothing. And sometimes, Mercy flops not because of how the player uses her, but simply the rank they’re in. Mercy is very easy to get value out of, but because of how her kit works, she’s actually worse in lower ranked play, as her teammates are less mechanically skilled, so half of Mercy’s kit, and the strongest part of Mercy’s kit, gets no value.
Mercy needs to be taken back into the workshop, and have her kinks hammered out. As of right now, her damage boost is carrying her through higher ranks, but in lower ranks she’s only got her reliability to go for, and it’s simply not enough. It’s fine if her kit is reliable, but if it’s not providing anything, you might as well be shooting your allies, the good your doing. And probably the best way to go about this is weakening her pocket capabilities, by reducing the potency of damage boost, but then giving Mercy more individuality by then buffing up (don’t freak out) Resurrect and Valkyrie.
Resurrect’s current power is incredibly misleading, at least in OW2. While the limitations of the ability are rightfully placed and fair, the environment of the game has changed so much that often its better to simply not use it, as fights end much more quickly and Resurrect takes too long to pull off, and leaves you with a single support to provide back up to your team. But if you buffed Resurrect while keeping Damage Boost exactly how it is, Mercy’s pick rate would likely skyrocket again, since there’d be no downside to her.
Valkyrie, on the other hand, doesn’t have Resurrect’s problems of being potentially overbearing, as its simply a bad ultimate. It was designed with Mercy’s original cooldown rez in mind, and it really shows. All it does for Mercy now is increase her movement speed by 2m/s, gives her infinite ammo (which, personally, never made any sense to begin with), increases her healing by 5, and enables her Regeneration passive.
Now, with all that being said, I want to propose some changes that could be a starting point for rebalancing Mercy, as that’s all she needs: A power adjustment. So, with that in mind, this is what I’d change:
