Please let master tier+ use the old champ select, and here's why.
Note: This post is directed to the new champion select (the part where you get to select roles), because there is no point in giving my thoughts on dynamic queue as everybody knows the issues in it by now. Also I am currently in challenger (14 lp).
As you can see by my image, I even went "Fill" and still got a 60 minute queue time. This is absurd and needs to stop.
Why? Because the little amount of playerbase + SELECTING YOUR ROLES. Before, my average queue time was 5 minutes, now it is about 20-ish minutes. Legends say I am still waiting to this day. Anyways before you get paired up with 4 random players not matter the role just on mmr, but now you are basically stuffing a bowling ball into a water hose with the role pick. The lack of players are just never going to work with this idea, BUT it is amazing in lower elos because there are just simply wayyyyy more players.
Solution? Allow master+ players get the OLD champ select, it is honestly perfect the way it is since the low amount of players. And elos lower than master get the NEW champ select (allowing them to choose roles.)
This makes the most sense, because in Master/Challenger we know everybody, so we pretty much just give our role up anyways to the better player (just like the old champ select.)
TL:DR Allow master+ players get the old champ select and lower tier players get the new champ select, for better queue times and experience!
Edit #1: I have no idea why my image is so big, sorry about that.
