From your second season in ranked onward, you can NEVER be placed above Bronze

That's the way the system works. You just get placed in Bronze. Nobody can deny this. No amount of evidence refutes this. Anyone who says otherwise is lying.

It's fact. You will be placed in Bronze.

######That is, if you have Bronze MMR before the season starts and underperform in your placements. Even then you might land in Silver, depending on your previous rank, but eh, it's 100% fact anyway.
