Neglecting a lane as a jungler should be a reportable offense.
Lets put this into perspective. Let's say you have a Draven ADC on your team and your playing Lee Sin, the highest ganks per minute jungler in the game. You notice that he got counter picked, thus you decide to not gank his lane at all, as he's dying under tower. Well, guess what you have there pal, a worthless ADC who is designed to snowball early. I can't stand it when I'm in lane, and pushed to my tower, dying. That is inexcusable. You're actually making a player on your team worthless because you're too stubborn to gank their lane because they got counter picked. The minds of some people.
