i need help pls..

Hey guys my mouse broked since 3months ago it's a Hp x500 I was having an insane mechanics and playing comfortably in all my games

So I decided to buy a new one it's a rampage smx-13.. when I start playing and practicing with the new one I felt like the mouse is so damn heavy 175g and I can't get used to it + my mouse cable is effecting the mouse when I move it to left or right I don't feel that its moving smoothly cuz the cable BTW I played like 2 months with it with 50% of my old performance (mechanics) So I decided to buy w rampage smx r9 well it's kinda good weight (150g) but the mouse cable is doing the same shhiit as before I can't move it smoothly + the mouse has no software u can only change it with a button (800-1200-1600-2200) so I can't adjust to my own dpi (1700) so someone told to buy w mousepad maybe it will be more smooth... So I bought a one and it's the same thing

I litearly start crying thinking about how I was and what I'm in now it hurts when u see a bronze player out playing u cuz didn't dodge his skillshots cuz the mouse or losing a team fight cuz u don't have an enough mechanics to click on adc and dodge kathrus Q's in the same time

I've been like that since 8months now pls help me to back guys pls...
