ABORT! ABORT! ABORT!

There seriously needs to be an option or opportunity to eject yourself from games without penalty. So many times I have gone into a Draft Pick (rank more often than not) and either A) Ran into someone (or multiple people) who was offensive and toxic right out the bat, or B) Completely disregarded the picks of their teammates and chose a role that had already been taken. Situations like this absolutely suck, because you're in a lose-lose situation; either you play through the game and end up having a miserable game experience, lose at least 20 minutes (and in Ranked 20-some IP) of your time, and all you can do is submit a report that you never hear back on, or you dodge the game, get penalized at least five minutes before you can play another game (and in Ranked lose some LP anyways), and can't do anything about the offending players.

My personal suggestion is that you give players a button to hit when it's obvious that the "teammates" are a legitimate problem, and then afterwards allow them to submit a report like a variant of the post-game screen, explaining why they opted to abort the game. Obviously this suggestion is imperfect, as there's nothing about how to keep people from abusing it so they never have to compromise or play anything except what they want to. But even without this half-baked suggestion, the point is there; people shouldn't be penalized for wanting to avoid playing with obviously toxic players, either by being forced to play through 20 minutes with said toxicity or being punished for "justified dodging".
