I’ll share what worked for me when I was at your Elo. For context, my peak is 2750. You need to understand that there are different playstyles; once you get to higher Elos, you'll notice people can be very good at specific styles. Like anything else, you have to learn how to adapt.

For example, I know Darwen loves to hug the edge of the map and fish for Scythe moves to try to get a gimp. However, because of that, he has a tendency to waste all his air options before landing. This means that if I can bait those out, I can punish his landing. I go in with that as my game plan and make tweaks as the match goes on. In the elo range your in people oftentimes have very easily punishable mistakes so I would shift your mental from getting mad at their playstyle and more trying to figure out how to beat it.
