Overwatch 2 feels like the exact same game. However, in the first few seasons of ranked, they completely messed up the systems. They've 'rectified' it now but a lot of the damage was already done and the system they put into place to try fix it was mediocre. They've said they'll be making even more ranked changes next season but I'm not very hopeful.
I'm glad they're adding more heroes but all in all, It doesn't feel all too special. The influx of new players also has decreased skill celling a lot.
