User blog comment:Commander Marko/The advantage of Duo Queue/@comment-5266525-20130921145912

As someone who exclusively duo queues, mid/jungle is the combination I've found to be in the best position to carry games with regularity because those two positions have the best roaming potential out of all of them. Most duo queue partners that I've had main mid lane.

Not saying top is a bad lane to feed at all, just that it's very isolated and your team's going to be at a disadvantage elsewhere on the map while you're busy up there.
