Went into my promos with 82 percent overall win rate. your ranked system SUCKS

Was getting double promod through to plat. No problems so far but as SOON as my mmr hits plat 3 ( the cancer d5 hard stuck mmr level) i start running into issues

i failed TWO PROMO SERIES due to HARDCORE inters ragers afkers and other nonsense. The game doesn't reward me for doing well individually but its a solo q game

where is the bonus points for me crushing and hard carrying my wins or doing well in losses. It's impossible for me to carry a game when bot goes 2-12 at 10mins and then i'm expected to not be upset at anyone too.
