i have started feeling very uncomfortable with my aiming it feels very shaky and when i lower my sens and dpi it becomes so slow that i cant even my crosshair .
it has killed the confidence i had in my aim helpp!!!!!!!!
first question i would ask is do you have a good setup? if yes, that is great.
my advice for you to find your sensitivity (there are youtube videos about it but basically, you need to aim at one of the bots head and start moving, while moving you should easily keep track of the head, if you cant do it rn you should change your sens. (when you find the sens that fits you, you need to work daily on aimlab and polygon)
if you give more time your aim will be good, you just need to work on it.
the game is not only about aiming but if you have a good aim you can make very hard situations winnable. you also need to work on custom maps and find the best angles, work on agent abilities.
then you just enter the ranked and if you are lucky you will have good teammates, if you don't you just need to make the best out of it
Happens to me all the time. Some weeks I feel like god and super comfortable with my aim and then next week I feel like I can't hit anything and feel super uncomfortable. Weird thing. I guess its also mental thing to some degree. When you feel confident you play better most of times while wise versa if you don't trust your own aim then you won't play well. Usually get really frustrated, so that doesn't help at all. I usually change mice, mousepads and sens during this, but its not good, just better to stay with old unless you truly believe its the sens that is stopping you.
