this is the only good opinion about ranking up and where strats are real worth:
silver1-4 = not a lot of stats, too unpredictable. you need aim because gunfights are everything
sm-gn1 = you still dont need ton of strats, please learn some game sense. aim is getting more needed, gunfights will be harder
gn2-gn3 = please learn game sense, you need them. learn smokes and flashes - they can win games. aim is pretty awesome to have, learn to either use ak/m4 or awp well, be useful
gnm-mg2 = aim required, flamers approach in numbers if you cant be useful. stay with the team. learn more smokes and flashes. aim aim aim one click aim aim aim one clickkkk
if you make it to mge you dont need my help

silver1-4= peak once, step back aim with awp wait for them to peak=profit
