New Champ Select problems

tldr : Trolls ruin new champion select

So this isn't going to be a hate rant on the new champ select. I like it a lot. The problem is the people using it. Twice in a row now, I have had problems resulting in me dodging game due to not wanting to have to play a game for 20+ minutes with the people I was on a team with. In the first game, I declared I wanted to play Yasuo, and I was mid. Our support wanted to play Dr. Mundo. The enemies banned him, and I said "Rip Mundo Support". When it got to our supports turn to ban, he banned Yasuo, and said "Rip Yasuo Mid". After everyone on the team told me off for my joking comment, and congratulated him for standing up to me, I dodged. I waited out the timer, and tried to play again. Once more, I got mid, and declared Yasuo. The problem was, our team was a premade of 3, and me and another random. One of the premade people chose mid as primary and bot as secondary. Upon getting bot, they declared they were going mid, and declared talon. I told him that wasn't allowed, he was dealt bot and had to play bot. I'm sure most of us have been in this situation before. However, what most of us don't do, is keep insisting that they would get the lane. I was able to ban, so I banned the champ he said he was going to play in an attempt to get him to go bot like he was supposed to. Instead, it enticed him to cursing at me, and therefore, not wanting to play with his premade, I dodged again.

The issue with this problem, is there's no real way to fix it. Trolls will be trolls no matter what. Unless there becomes some way to vote a player off the team or vote to dissolve the team and reenter queue, this problem will be the same. However, if this happens, then troll premades will come up who kick people like me off their teams.

So, the reason for making this thread, is to try to come up with solutions, and eventually maybe have Riot make a system where this cannot happen.
