I’m imm3 now and I feel like most of my deaths are results of my bottish movement which allows me to get killed easily(?) is this a thing? How do you all improve on that?

A lot of player from sea server are always dc cause of high ping, Me and my team force to surrender because its 3 v 5 and we cannot remake anymore. I always encounter this type of situation and i have to deal with it but please do something...
