Reading back on the context, I thought most people didn’t want to balance around the top tiers?
Unless that’s your personal opinion, then I’ll respect that. But in general I found the forums hated balancing around the top 5% of the playerbase
There’s not enough support heroes to have the same distribution as dps. And there are healers similar in pickrate. Lucio and Zen are very similar in pickrate. Mercy’s not that far ahead.
Now look at the winrates in those elo. In gold and below she has the lowest of all the main supports.
In Plat+ Moira isn’t an option because of how weak she is without any sort of Utility
That means only Mercy is Ana’s competition. Mercy works in DPS heavy comps, 3-4 DPS.
The meta on ladder is more bunker, which means Baptiste and Ana are going to see more playtime
Mercy and her have simply switched positions. Mercy did not deserve her last nerf and Ana doesn’t deserve one now.
Just saying, the classic bunker comp now is mercy bap for supports
Baptiste has been seeing lower playtime steadily ever since his peak. He’s not a requirement.
My bad, sorry about that
Also meta on ladder is still mainly deathball, not bunker. Bunker and 4 dps is mercy’s territory rn and deathball is ana’s (as it is basically just a ball)
Winrates really are secondary to pickrates in terms of assessing hero power. It just means that people on Mercy and Moira will more readily switch off those characters (likely to Ana), which causes their winrates to inflate and Ana’s to deflate.
As for Silver/Bronze… yeah, she should ostensibly have a lower winrate and pickrate both considering she’s supposedly a higher-skill-floor healer compared to Mercy and Moira, but what’s troubling is that she’s isn’t that far behind them. Meanwhile, she dominates every other rank by a huge margin. That… is kind of an issue.
Winrates + pickrates to assess power in general. They have basically the same pickrates in these elos, and still ana’s winrate is lower. And I don’t see why someone’d swap off to ana when losing, as those are the elos where I’d expect them to realize they’re “not the best” at aiming her heals
I basically already talked about this… if you want, you could say they’re about even in Gold. Ana’s still a decent bit ahead in pickrate but a little behind in winrate. Realistically that still suggests she’s the better support (because if winrate was truly indicative that Moira and Mercy were better, then it stands to reason they’d be chosen more–if they were truly better, then why not be used more?), and even in Bronze/Silver, if her lower winrate was indicative that she were bad, it doesn’t explain why people insist on using a “bad” hero at levels comparable to the “good” heroes. This is why pickrate is the more informative stat–winrate is more a seconary analysis to suggest how that hero performs in their niche, and if people tend to switch off that hero or stay on that hero when losing.
Because her Bionade and Nano are extremely powerful, and people are likely willing to sacrifice healing (which… saying that people recognize that they’re not good at healing in Bronze/Silver is being a little generous) to obtain those abilities. Bionade is arguably one of the strongest non-ultimate abilities in the game and has the ability to swing a teamfight on its own–even in Bronze, that’s a very tempting tool. And then Nano-Boosted Reinhardt is practically a free teamfight win in low ranks, so that’s another factor. Ana has a lot going for her beyond just healing–she has some of the strongest utilities in the game.
Because healing tanks sure is hard as Ana right? 
ngl but if sym ever becomes more predominant as in not just a niche tp pick for 1 point, someone who actually can hold her own place,ana will in fact start to fall
Because healing that spazzy genji is sure as hell easy as ana amirite.
Also the fact that there’s no peal and the ana definitely can’t land sleeps
I feel like in gold it’s purely a mentality that ana is better, even though the players still aren’t good enough. This isn’t shown in stats though and a poll might be better.
Landing a bionade behind a shield is going to be hard in bronze, and it’d probably be used more for healing I bet, again sadly not shown in the stats.
Even still, let’s say everything I’m saying is wrong, it still shows that Ana isn’t overtuned for most of the playerbase and is more on equal footing, and is only more powerful in the higher elos where only then can they maximize her usage.
And yet, everyone is crying about nerfing Widowmaker yet she’s not even top 5 pick rate here.
They just need to give Moira better healing range and make her juice replenish faster so she can compete with Ana. Ana has a lot of reliable counters, so I don’t think she needs a hard nerf… it’s just the other main healers are a bit… too niche right now.
Because Ana is fun to use and fight against.
