Call me toxic, but if your mid lane is 0/8, and your bot lane is 1/7 by the 20 minute mark...
I'm not going to play, simple as that. If my team can't handle their own shit, then why should I get punished by trying to 1v5? I'd rather take the -18 lp. That's just me though, some players just do not deserve to win that game after they made the same mistake 3 times in a row during laning phase.
