Troll picking ranked games

I'm now on a 14 day ban because I lost my temper when my adc decided to play veigar (no history of playing veigar as adc before) then not connecting for the first 5 minutes of game. This isn't about the ban because that was fair, can't argue really other than saying it was one time and I've been honor 5 the past two season.. However, how do you deal with players, particularly when you are playing adc & support who pick super off meta with no warning? In retrospect I should have dodged but it a) sucks to be put in that position, b) feels like you are being asked to sit in a lane and lose while someone else is playtesting a build? Just venting.
