I have lost every desire to play ranked.

Pointless now, as compared to when? In the echo chambers of Hashinshin, everyone seems to have forgotten that the reason you are able to hold a certain rank is because you are good enough to be there. You can still climb like always. Nothing has changed in that regard.

The enemy team always has 5 unknowns, while your team has 4 unknowns and you. Improve yourself, and over many games you will climb to where you belong. You can't win every game and you have to accept that.
