Overwatch competitive is mechanically simple? Are you for real? Have you seen how much people struggle with basic facets of the game like team comp, or how to tank? Between high plat to mid-diamond Overwatch is probably the most toxic game on the planet due to the players at that rank being able to hit targets but mostly lacking any game sense.
Also, you're simply wrong about the impact the additions to the game have had. Sure, it would have been nice to have more, but they added Ana, Brig, Moira, Orisa, and Doomfirst, to name the heroes with most impact. All of those characters have completely changed the game. Their kit is entirely balanced around the competitive game mode.
Mechanically as in the complexity of the gameplay systems, complexity does not equal depth, difficulty, or nuance.
IE you could more content for the game than just 'online PvP stuff' without having to balance heroes particularly for things like PvE etc, and in doing so would not effect the PvP game. It's one of the benefits of the game being made for PvP first instead of the problem that MMOs run into with being built around PvE w basic AI and mobs, and then figuring out ways to make PvP balanced (often resulting in seoerate gear types etc).
Just curious, do you also want a single player/campaign mode for Counter Strike or Rocket League?
I wouldn't say so. The thing with overwatch is that a massive part of its appeal lies in the characters, world, and lore. That's why people want more than just 'new map and hero' with what can barely be called drip feeding; they want more access into experiencing overwatch actively. It's the same reason why you can have overwatch comic books than people eat up. Overwatch is presented in character/narrative terms that the others simply as not.
What an odd thing to read about a Blizzard property. I guess modern Blizzard is really that far removed from classic Blizzard.
IMO, it's just a bad take from someone who narrowly engages with the property. It's cool that is all Overwatch really is to them, but that's not represented in the fan base as a whole.
Terrible idea, why give up the roster you have now to reset it? They have much bigger problems than needing a new game. All of which they can address on this platform if they cared enough to do so. They just don't.
It's extremely doubtful that they have been allowed to attempt letting Overwatch live up to its potential. They have to satisfy the shareholders first and that means that the games bery monetization ethos was pitched as 'doing the least work for the fastest return that can keep the engagement pool just satisfied enough over a protracted period of time' instead of having a roadmap to make meaningful additions to it that would cost money, time, and would be seen as risks.
If all of that CG/Comic and other movie from the budget had gone into more ambition in updating the base game, or had there been more ambition and no shareholders to disproportionately serve first and foremost, Overwatch would be bigger than it currently is and a better game.
Again, an example of doing it right from a game that started as a barely functional and extremely limited corridor grinder
