The last game this happened to me:
Me- calls and is given jung
Me- "I'll Sion, Udyr, or Trundle"
First pick- bans Sion, Udyr and Trundle, locks in jungle Yi after he called ADC
Me- "Bruh really?"
First pick- "bet you're only picking them because they're FOTM"
Me- "lolwat, of them only Sion is FOTM, and I played him as a jungler even before Cinderhulk made him broken"
First pick- "dun care, dont trust a random to play them. Bet you'll farm all game and be toxic when you never gank"
Me- forced to play ADC, "I uh...suck at ADC"
Team- argues a bunch and so I pick Twitch vs their Kalista
16 minutes later:
Master Yi to "prove a point" tries and fails to gank every lane to the point he's 0/6 and he's lvl 6 when the rest of us are 8+
Team's arguing, Master Yi shouts in all-chat how scrubby I am because the enemy Kalista's fed when in fact I'm 0/0 and the Kalista is 4/0 off of Yi and Kat (who also failed multiple ganks), but ignores the fact she's down literally 50 CS
20 minutes:
Team tries to surrender, I vote no because I see the game is winnable (200 CS while everyone on the enemy team has only around 100 (yeah, this was when my MMR was crap and I played with Silvers)) and Yi votes no to be a troll
40 minutes:
We win, I'm 18/4/20, Yi shuts up around the 30 minute mark when I get a Quadra
Me- "Yi, don't ban my mains and maybe the game'll be less painful yeah?"
Yi- Leaves
