lived so long to see my self become one of those who hold good players back :(, the training arc starts now though. I will make a new account and hard grind all the way from IRON
maybe aim to stop flexing onto too many roles/agents as you can start to be inconsistent if you don't have full mastery of one agent's kit for a map. Try to aim for playing one set agent per map and get as comfortable as you can with said agent. Just my two cents take it with a grain of salt
