It’s been almost 2 months since the Mercy nerf, and the fact that she’s currently in a bad state is becoming widely accepted. I think it’s reasonable to assume that at some point in the future she’ll get a buff.
One buff that I see suggested quite often is to increase her healing to 55 hps. The reasoning goes like this: She used to be considered OP back when her healing was 60 hps; She’s considered UP now that her healing is 50 hps; 55 is a number between 50 and 60.
I think that making this change would be a mistake. Most of the changes to Mercy over the past year have been entirely reactive. Pick rates goes up, she gets a nerf (or the opposite in this case). It’s been very long since her kit was approached from the point of view principles of design rather than balance, and it shows. She’s drifted from her intended role into something rather different. The 55 hps change would be just another link in this chain of changes.
The fact of the matter is that Mercy wasn’t nerfed because she healed too much. She was nerfed because she was picked too much. We know this for several reasons. For one, the devs considered her to be balanced numerous times when she had the same amount of healing (the last of which was in May). The only thing that changed from May to July was her pick rate. She was considered underpowered when she had the same healing pre-rework (her healing averages back then were very similar to what they were post rework).
Another reason that we know this is that Moira currently heals just as much on average as Mercy did prior to the nerf and no one ever suggests nerfing Moira’s heals. (To forestall any objection here: yes, Mercy is more consistent than Moira. But Moira has higher burst and aoe. Mercy is better for long fights, Moira for short fights. Mercy is better for spread out teams, Moira for bunched up teams. Mercy works better with dps, Moira with tanks, etc. They both have advantages and disadvantages, but the fact stands that healing totals can’t be what caused the Mercy nerf).
The main effect of the healing nerf is that Mercy currently struggles to fill the main healer role, and is relegated more to an off healer role. This is a problem. According to the devs, Mercy is meant to be the go to character for healing throughput, and that her main attribute is meant to be high healing throughput. She’s designed to be a main healer and has currently drifted out of that spot. This shouldn’t be surprising - she’s had 50 hps before and struggled to be a main healer.
If Mercy is to work as intended, she needs to be a main healer. In order to be a main healer, she needs a certain amount of healing. We know that 60 hps works, and we know that 50 hps doesn’t. Does 55 hps work? No one knows. Blizzard doesn’t, they’ve clearly struggled with evaluating Mercy and predicting where changes will lead. None of the people suggesting this change know either. It’s compromise for the sake of compromise, without any real reason to believe that it will work. It’s just more drift without forethought.
What happens if 55 is underpowered? Do they change it to 57? 58? And if it’s overpowered, does it go to 52? It might take quite a long time to get it right.
Nerfing Mercy’s healing was always a mistake. They carelessly messed with the heart of the character in a desperate ploy to get her pick rates down, and the effects were far from what they foresaw (or what they claimed they foresaw). It was too risky a move.
The healing should have stayed, and should return to 60 where we know it works. The other healers received significant buffs, but even if those would not have been enough there were other ways to change Mercy. Changing her healing is simply too volatile a way to balance her. It’s unpredictable, and it causes huge swings.
Keeping it at 60 hps opens the door for some interesting balance changes to the character. There’s no question that elements of Mercy’s current kit have proven to be controversial and difficult to balance properly. Res and Valkyrie are the main culprits here. There are so many interesting things that could be done with these that would affect both her balance and her gameplay and would address some community concerns. I think there’s a large community that would be happy with such changes.
One simple example is removing chain healing beams in Valkyrie in exchange for a somewhat stronger main beam. This would have the effect of being both a healing nerf, and a way of making Valkyrie feel more impactful and engaging.
If 55 hps is currently the best idea that Blizzard has then I suggest they just leave her as she is for the time being. They should take time, think her through from first principles, and come back to her when they have a better idea. This election cycle, vote NO on proposition 55.
