You REALLY have to do something for the punishment of leaving champ select when meeting trolls

Losing LP in this situation is so unfaire, like really unfaire. I'm in such a bad loss streak these days, and I regulary have to exit champ select cause an idiot original player thinks he can win as Jinx top or Shaco mid (I beforehand checked the profile and saw that the guy wasn't good with this exotic pick). After leaving, you get a 5 minutes leaver buster and lost LP. That's so annoying and frustrating.
