sounds stupid to some of you im sure but for those of us who are good enough to be in silver or gold an end up on losing streaks for a month it kinda make us wana give up :| even more so whenn you get shoved back down in bronze and things become unwinnable
If you're in a month long losing streak, maybe you really aren't good enough to be a gold or silver player.
It's not like skill or your skill relative to others is constant. You could have been silver or gold skill level at one point, but not anymore. If you are playing 2 or even just 1 entire tier bellow your ability you should win a vast majority of your games. If you aren't the overwhelmingly most likely scenario is that you belong there.
If you spend a month playing at bronze level, why would you be become bronze?
If there were no demotions then ranks would be completely meaningless. It would be like masteries, they tell you nothing of someones skill with a champion. The only thing they tell you is that they have played that champion. Ranks are a measurement, not not an xp bar to be grinded out.
