Needed adjustment for 10 ban system
First, I'm enjoying the new 10 ban system and applaud Riot for making this happen. My only request, don't let your team mates ban your declared champion.
This weekend I had a case were the ADC didn't like my choice of support, Miss Fortune, and proceeded to ban my declared champion. This was in a normal draft match, I qued up with the intentions of practicing Miss Fortune in the support role so I could play her in ranked games. There was no discussion, they just banned MF. Luckily they rage quit when I selected Ziggs for support, but this is not a good situation.
Since you clearly mark intended champions, just make it so they can't be banned by your team.
