Good morning Ayeziza,
Piggy-backing on what Adam said - I don’t think this is an unpopular opinion, but creating asymmetrical balance between 86 Heroes is very delicate work (and has been finely tuned now for over 5 years).
We do our best to keep the vast majority of Heroe’s win-rates between 45% and 55% (currently 79/86 or ~92% of the Hero roster sits in these bounds). This is data from Diamond+ Storm League players and gets even tighter when we look at the whole population, including Quick Match.
There is a huge amount of risk with shifting the current balance of Heroes upwards, but there is a sweet-spot that we can hit where a Hero can feel OP but actually be well-balanced. We are doing our best to find the current outliers that don’t have those moments and make design or balance changes to help find them =)
