This is what's wrong with this community
I go into solo q and Darius does not get banned. One of my teammates immediately says "gg" and resorts to a troll Leona top pick. I tell him it's not that big of a deal because Darius got nerfed. He tells me that Darius did not get nerfed (right, yeah, because I'm not the one that read the patch notes). This player continues to rage in champion select, saying "I'll show you how OP Darius is" (implying he will feed). The game is lost before the match even begins.
The problem this community has is refusing to learn how to play against champions. Also, if you don't get what you want, you adapt your play style. Completely childish to rage and troll when you don't get your way, this is ESPECIALLY true in ranked. Ranked is where you go to prove your skills that you've gained in normals (like the ability to play against Darius). I will fully support any system Riot enforces where you need to prove yourself before being able to enter ranked queues.
Oh and thankfully someone dodged that queue, whew!
