Any tips and things i should improve on? I started playing PC about 4 days ago from console and im enjoying it but in terms of aiming, movement and so on sometimes i still struggle so what should I do to improve those things? I play on an old amazon keyboard 😭 the reload key barely works and
sometimes my a key doesn't want to work either. everything im using is pretty low end and im not in any position to upgrade so what can I do to improve because I know people have hit high ranks with low end peripherals
