Agreed with OP. Stick the filth with the others..
In order to help a bit with these mindless fools I generally duo q and me and my friend fill in spots and we try to get everyone where they want to go, even if we are first picks. Why? Because I have had so many games where people either afk, feed, or just verbally harass other teammates (mostly the jungler, because we all know they are the scapegoat when a lane is doing bad.) And when you try to help them, they really do always say "stfu" or "Be quiet fggot." It is so annoying to have to report people but I am always finding myself throwing out a report a game, its pathetic. I'm not going to help anyone who is being a complete dick to me just for trying to either help them with their build, or if its just general tactics. Maybe we could have an IQ test placement for players..
