I can only hit two bots on hard mode when I'm training. it's unbelievably fast for me. same when I'm in a game and I have more than one opponents and stuff like that. I'm super slow to react and unaware of my surroundings, I really don't know how to improve it. I've trained my aim really hard and it's gotten good but it's not that helpful if I cant react. my reaction time is between 270-330 ms
