Overwatch is an objectively better game now than it was in 2019, and it's not even close. You are wrong, and I find it hilarious that you want a "deep, thoughtful apology".

Role lock and 5v5 have dramatically improved the health of the game. They've made matches more even, lessened toxicity, improved queue times, improved player experience, improved game balance, and made the game more dynamic. There are definitely drawbacks: tank synergies like Reinhardt/Zarya or Winston/Dva were fun, and having the option to play triple damage or GOATS or whatever was cool. But the tradeoff is so overwhelmingly positive that it kind of blows my mind that people want to go back to 2019 Overwatch.
