No, those players are stuck in Silver, where everyone just locks their main and go play.
Meta is made by the players who have a basic understanding of the game and balance.
Regardless of what you want to believe meta exists. It’s not as concrete as some people think though. Some heroes are great in some maps or on some points. For example, Genji and Tracer are meta DPS Heroes right now. With their stats and the stats of other heroes, they are unparalleled in their ability to get into the back lines quickly, kill the Supports and get out safely. That doesn’t mean all other DPS Heroes are bad. Soldier and McCree can still be great picks, especially when they can use high ground to their advantage. And Reaper is good where it’s close quarters and the other team don’t have good access to high ground.
Orisa is good on some maps where there are few flanks options, especially with a Torb. And she’s good on Nepal Sanctum. However, she lacks the mobility, burst damage and damage mitigation of Dva and Winston (yes, both Dva and Winston have surprising amounts of Burst potential). Orisa can do nothing to help healers from flankers. And as I said, the best 2 DPS right now are Genji and Tracer, thus Orisa is almost obsolete.
This increase shields size and and faster projectile speed will hopefully make her job of helping supports a little easier.
