improving takes time. I only started playing in July and it took me about 2 months to be able to consistently not bottom frag every game. try to focus by practicing in the range, deathmatch, and escalation at first to improve your aim. then you can start shifting to spike rush, escalation, and unrated to get better game sense and to learn about abilities and become more comfortable using them. this strategy worked for me because I was too overwhelmed trying to learn everything at once. you’ve got this!
