This is when you should dodge

When you queue up a match and get your highest win rate champion for a role banned by someone on your team like this. Oh and for extra points they received the adc role and insta locked jhin with a total of 6 games played on him in account history.
Remember to always look up your teamates in champion select. The 5 lp hit is better than a loss (I regretful do not do this enough).
At least my first pick mid lane Zed that got banned is level 5 mastery and has a match history of 9 out of the last 11 games won (2 of them ranked, the rest norms).
