Dynamic Q has made this a game of RNG
I say this because, you now have a much higher chance of having someone on your team that is boosted, you have a chance of getting someone that is easily tilted and rages at the team, you have a chance of getting someone that intentionally feeds or trolls, you have a chance of getting someone that plays hundreds of normal games and decides to Q for ranked when you do, you have a chance of not getting your primary role and instead a roll that you are not 100% confident of being able to carry a game with, you have a chance of getting matched with people much outside your skill level, and if you so happen to get through all of this RNG and the game is normal, you run the chance of getting an AFK at the start of the game and having to remake and go through the chance of getting all of this once again.
