Dodging should not make you lose LP
Especially until a PROPER ranked matchmaking system beyond everyone getting into a room and hoping their main roles fall in line.
I should NOT have to deal with someone who is a "toxic" asshole literally less than 2 minutes into champ select, because they didn't get a ban they wanted. I should NOT have to choose whether I get a drop in LP for avoiding a game with someone who threatens to AFK if they don't get their role as last pick I should NOT have to go into a queue with a 20% chance of playing what I like to play and hoping the other 4 people had the courtesy to do more than "only know how to play X" thinking they're ready for ranked.
This should have been fixed years ago. We're in season 4, and if matchmaking with actual player interest in mind is not a priority, then Riot, you need to be the ones to bite the bullet for once on this, not the players.
Yes, people should band together despite disadvantage and try for a win. Yes, people should accept they won't get their role every time, or be firstpick every time. That is not reality, Riot, and it's well past time you guys realize that and do something about it. Losing a game because some douchebag didn't get to play ADC (the only role he knows how to play yet thinks he's ready for ranked) and decides to throw himself at the enemy team saying "lol should've let me have adc" IS NOT A MEASURE OF ANYONE'S GODDAMN SKILL.
I don't give 2 shits if some guy I will literally never see again gets banned for intentionally feeding, what I care about, what I'm sure almost everyone cares about, then, right there, when they're doing that, is "man, I wish this could've been avoided", which would happen if there was actual matchmaking focused on players. Sure, that same guy might still be a toxic asshole, and might still cost us the game, but at least he might try to win for the first 10 minutes.
Players are held ransom by the will of douchebags and the inability to avoid guranteed problem games without suffering, and it's apparently not high enough on the list for Riot to fix even years into the game's existence. Team Builder is a step in the right direction, but at this rate it'll be YEARS before we see any kind of ranked implementation.
