Riot Created Prisoner Island. Its called Normal Draft.
So people have often asked Riot to take the Dota approach of putting toxic elements into their own que together. Riot has consistently stated they refuse to do this at least in part because they believe it doesnt really help solve anything. I assume that means they think its better to try to reform players than just segregate the most toxic ones from everyone else.
Then they started a system of restricting people from ranked as a punishment and the way they lift that restriction is only by winning normal draft games. Riot argued that because the numbers of ranked restricted were such a small percentage of the player base that it wouldnt noticeably impact that quality of normal draft games. From my experience that has proven to be untrue.
I have not wanted to start ranked yet this season for a variety of reasons. That leaves me with my most played mode being normal draft. I really like having a draft phase and I think honing pick/ban strategies in normal draft mode is the best way for me to practice for my eventual return to ranked. I cant stand blind pick and Team Builders still takes too long to get a game going, even when I que up as support. I can only imagine how long it takes for other roles.
I have never seen normal draft in a worse state. Every other game has people raging or blatantly trolling from the start. I wish that was an exaggeration but its been amazingly bad. I am not sure if a new wave of people just got rank restricted over the last couple of weeks but it seems to have gotten markedly worse. People seem more angry to be stuck in normal draft than eager to win games and get back to ranked. This experiment seems to be an utter failure.
Riot has created a prisoner island, something they said they would not do, but even worse to do so they ruined a game mode that for many of us is our most played mode. So instead of a real prisoner island where the toxic folks can at least get a taste of their own medicine as a reward for their behavior, its actually a bunch of non-toxic folks that also bear the brunt of this.
So Riot, either create a real prisoner island that is reserved for only those being punished, or just scrap this whole approach all together. There is no possible way to justify punishing solely people who play normal draft because of toxic elements you cant figure out what to do with.
