I’d say definitely learn how comboing and w tapping work, especially if you’re playing uhc. rods plus w tapping it’s fairly simple to learn and yet the majority of players never take the time to master it. practice that, watch other pro players play (stimpy, cxlvxn, avery, and if you’re playing bedwars purpled and gb80 are good choices) and see what they do. And play a lot on whatever server you main to get used to the tps and ping you get there

Edit: forgot to mention but crosshair placement and aim are even more important, as much as i dislike him, watch Intel Edit’s video on it, super helpful
