Need a vote kick option for champ select

I seriously think we need a pre-game option to somehow dodge a trolls before the game even starts.... Just ran into this situation 2 consecutive times. First game the midlaner start flaming the jungler (he is gona be useless, wont gank, etc...) then the guy gets pissed and picks teemo jungle....

The next game started like this (player1 banned player2's yas) (I'm such a cool guy for replacing nicks tho...)

> [player 1]: get kys > [player 2]: ? > [player 2]: you're such a big man arent you > [player 2]: tell me though > [player 1]: 176cm and 49kg > [player 1]: 11cm > [player 2]: was it the 4th or 5th floor they dropped you out of as a baby > [player 2]: oh no hang on i remember > [player 2]: it was the 6th > [player 2]: you know what > [player 2]: ill jungle > [player 2]: thanks > [player 1]: ? > [player 1]: im jungle > [player 2]: nope > [player 2]: you bm > [player 2]: ban my champ > [player 1]: yes? > [player 2]: think you are cool as shit > [player 2]: MATE > [player 2]: HE BANNED MY SHIT > [player 2]: INSTANTLY > [player 1]: im not going to play a game with YASUO MID XD > [player 2]: XdxxF > [player 2]: #FZD > [player 2]: \SEDA > [player 2]: R EDF\S > [player 2]: FGZXSD

So maybe some kind of a non-abusable dodge solution would be great, where you can kick out one player with a majority of 4. (The abuse part would be obviously the dodge of unfavorable matchups). Or even better the system may look for another player for that position...
