Support Secondary Role is a bit like Prisoner's Dilemma
Wikipedia Two members of a criminal gang are arrested and imprisoned. Each prisoner is in solitary confinement with no means of communicating with the other. The prosecutors lack sufficient evidence to convict the pair on the principal charge. They hope to get both sentenced to a year in prison on a lesser charge. Simultaneously, the prosecutors offer each prisoner a bargain. Each prisoner is given the opportunity either to: betray the other by testifying that the other committed the crime, or to cooperate with the other by remaining silent. The offer is: If A and B each betray the other, each of them serves 2 years in prison If A betrays B but B remains silent, A will be set free and B will serve 3 years in prison (and vice versa) If A and B both remain silent, both of them will only serve 1 year in prison (on the lesser charge)
This reminds me of choosing support as a role, if you don't want to support every game.
Person A is willing to support 20% of the time Person B is willing to support 20% of the time Person C is willing to support 20% of the time Person D is willing to support 0% of the time Person E is willing to support 0% of the time
A, B and C each start off supporting 33% of the time. Person C gives up first. Now Person A and B are each supporting 50% of the time. Person B could have dealt with 33%, but 50% pushes him over and he stops picking it too. Now Person A is supporting 100% of the time.
You see, if everyone was willing to support 20% of the time, everyone would be happy. But since in is not in Person E's interest to support, he won't. This increases the dissatisfaction of the other players, which feeds a self-perpetuating cycle.
Now this is a simplified version of events, but I think it does communicate some of what is actually going on in the larger scale of Dynamic Queue right now. Maybe not at all Elos, but at some.
Me? I don't mind. I'm maining support right now and I enjoy it. Get my role 95.5% of the time. Just some food for thought.
