That’s game sense through and through. To have a 66% win rate you should be able to know where the enemy is, where the pressures are likely to come from, what your main tanks situation is like. While burst damage ofc happens, Brigitte also has one of the most clutch burst heals in her 150 repair pack that goes into armor overheal. Can set someone up for a kill they’d be pressured away from, or get someone around a corner they’d otherwise die trying to reach.
Game sense, and when played with strong game sense, Brigitte is ridiculous outside of the highest tiers.
We are all bad players. The good players you are referring to are literally 1% or less of the overall population. And yeah, I even said her kit is kind of balanced, with highest tiers in mind, but outside of that, it’s ridiculous, as demonstrated by the winrates. The goal isn’t to prove some conclusion we came to through feeling, but to understand a situation and illuminate the details of it. Statistics help us in that illumination. Dismissing them is just willful ignorance. There’s margins of error in EVERYTHING. Inaccuracies in everything. Objective statistical data like pick and win rates offers us something to refer our anecdotes and experiences to. They are not to be dismissed or taken as gospel, they are to be considered.
Considering that, my own personal experience, and also what I have seen/thought about/considered, the most logical adjustment to Brigitte is to lower her shield health. It raises her skill floor, as you need to rely on game sense to mitigate damage, not just derping into a storm of projectile spam and such. Brigittes get away with too much throwing their body into stupid situations and coming out of it alive. Sure, it feels good when you do it, but it’s not good for the game as a whole.
Keep playing Orisa and see if she keeps up with your Brigitte in winrate, similar hours played. For you to be maintaining 60%+ winrates within your tier, after like 10 hours of playing, you are being matched with people you’re clearly better than. If you’re only achieving that on 1 hero, then that hero is possibly broken in the tier you’re playing in.
The matchmaker, the SR system, etc, tries to create matches where the teams have a 50/50 chance of winning. To have consistent 60% over a lot of hours is an issue. Especially if it’s only with 1 particular hero.
When we have THIS MANY PEOPLE having this level of success with one specific hero, to have such a wild variance in the overall average via Overbuff, for over a season, there is no way you can argue this isn’t a problem, or a huge deviation from the norm as far as this game and hero design is considered.
The obvious cause is probably a rock bottom skill floor. Lowering shield health raises that floor substantially, while having less of an impact at the highest tiers where team coordination and such make the individual shield health not very important. It’s not relied on often.
