WHY?!?

EVERY season whenever i get to S2 or S1, i get screwed over by trolls and afkers. Every time I get close to gold, I suddenly go on huge losing streaks. EVERY SEASON! Like I reach one point then for some reson I go to S4 or S5. Take a break after 2 games? Check. Never flame? Check. Report all the trolls and afkers? Check. But nothing get better.....Sigh...
