I need help to become at least below average :(

Dwigt: I'm not the best player to give advice but timing, map and minimap awareness, positioning and knowing your role are very important. Aiming and knowing each the weakspots will follow.Sharing replays with other players and platooning with others can help improve your gameplay. Comparing your stats to mine tells me that you like to rush in and have an aggressive playstyle? I might be wrong. Watching streamers and guides to understand how spotting and positioning works and trying those tactics on low tiers.Good luck man!
