Problem with people is their mentality, not the skill. If you really want to improve, you will not come and cry to G&R where you know everyone will post the obligatory "play more". A part of this "mentality issue" is not experimenting. Being afraid to change styles, optimizing game, tinkering sens. and so on. Been there - done that. In 70ish days I climbed from 120k to 78k rank with below average peripherals. So if a trash like me can do it, so can everyone. Just have in mind that altering universal offset will temporarily help you but screw you up in a long run.
Looking at these threads is kinda annoying -- there is no better feeling than solving your problems all by yourself, seeing progress and building self-esteem as a result. Overcome the obstacles without adopting bad habits.
