Placements Rank

So, this is actually the opposite of what yall might think it is, I'm a little triggered at the fact i was placed in plat 3. Now i know it may sound weird. My mmr was Plat 1 during preseason, and i expected probably around low gold maybe high silver, and got plat 3, which is really weird in itself. because i believe the system put me way too high i am getting screwed over in terms of LP gain, 13-15 a win, 21-24 a loss and I'm struggling to climb, even tho i was placed here. I really wish Rito could just put me in gold and let me climb back up to plat so my mmr can not be fuckered
