User blog comment:QuantumFeint/Botlane meta - where did all the supports go?/@comment-4091261-20140908040042

It's actually quite simple to understand why there are so many support-role champions that aren't traditional supports. There is only one duo lane in the current meta, that's bot lane. Guess where champions who rely on their allies go then to get the ball rolling: bot lane. If there were duo tops, then you would see many of these kinds of champions that aid other allies with utility but not physical stat buffs climb to the top lane instead. However the jungler role has become so significant for it's game changing power that people abandoned the notion of a duo top lane in the meta.

Jungling is quite a powerful role and I have nothing against it, though that is truly the reason why you see so many utility based champions in the bot lane. They have to find someone else to help take advantage of their utility and the jungler can't just sit around in top lane forever. So these champions just naturally migrate to a lane where their utility can be useful, a duo lane.
