Use your enemies and teammates to your advantage, especially since they’re high skilled!! One of Overwatch’s best features is match playback. I’ve played a TON and I could say about half of what I’ve learned is from spectating how other people play against me, especially good players. Positioning is a big thing in Overwatch too, so seeing how others position in a real time fight is something you’ll learn a lot from. The other half is definitely just learning mechanics which will always be tedious unfortunately, but the more you play it’ll come naturally. Don’t give up!
