WTF is this Rank System

You go on a losing streak, not because of yourself 90% of the time, and you then end with a bad winrrate and somehow Riot thinks it's okay for you to start losing more LP than you gain or start losing the same amount of LP you gain.

Wtf is that?

Just what is the reasoning behind this? You are trying to tell me I dont belong in the rank I earned?

So what now? You WANT me to get demoted to the rank the system thinks I deserve?

That, however, only happens when you LOSE games and in turn you LOSE MMR. So what? By the time you reach the rank the system thinks you deserve, you have lost too many games and have further sunk your MMR once again and it becomes an everlasting journey until you reach Iron. Oh well.

Riot, if you manage to hit the next rank your LP losses and Gains should be reset.

No reason as to why I should fall from Gold 3 to Silver 1 and end up losing more LP than I gain only to end up BACK in Gold 4 with the shitty gains and STILL gain less LP or equal to what I lose. Fucking bullshit.
