A problem, just like OW1, is that people watch streamers say something is OP and everyone chooses that meta. Nobody really wants to come up with interesting comps or strats, just a winning formula. It makes the game boring.

That has been my major problem with modern online gaming. Dataminers will find an “optimal” way, or some E-Sports player does some crazy dope high-level shit, or a popular influencer says XYZ, and ultimately has a big impact on the “meta”. I have hated that players have just become meta-slaves, and anyone who plays outside the current that meta is punished for it. It really reduces how player expression can exist. It is no longer “I like to play this game this way” it is now “Play it this way or don't play at all”. It's infinitely worse in games with gear or "builds", it really zaps the fun out of discovering new ways to play.
