in champion selection.....

Hi people:

This just happened multiple time in ranked game:

top lanner pre-selected Yasuo Mid lanner banned Yasuo person A:why did you banned yasuo? I am going to feed your lane (select soraka top)

Or

support: f**** I got antofilled, someone take support, I am going to be ADC (pick an adc) ADC: no! (pick an adc)

or

people lock in some unusually pick (like Sona top lane), and when we ask, he does not reply at all.

this happens alot, especially for low-rank soloque person like me.

What should I do with such game? should I go into the game knowing my chance of winning is considerably lower than other game? or should I just take a small LP lost and penalty time?

why not have a "disband" function where player can vote to disband a que? or a "free dodge per day" system to avoid this? or at least remove LP lost on 1st dodge (but keep time penalty)?
