Whenever I jump into Valorant I almost always get Ace or 4-players kills at the first and 2nd round of game, and then I start losing hard not getting a single kill until the switch. Do anyone know what I can do better to improve?

I decided to make up a Controller Agent because Controllers are Cool, Also it's because I am always forced to play controller in comp. https://preview.redd.it/ke4q6sp7vzv81.png?width=1955&format=png&auto=webp&s=5442ce69d712e20669f940739c62...
