Thing is, regardless of which lane you happen to play, the moment other lanes start feeding and you arent massively ahead yourself chances are......you cant do shit.
I´ve playing around everywhere for ages, i´ve seen everyone and everything common, and even some of the uncommon, feed or get fed.
I´ve had games as a marksman going 5,0,2 only to realize my toplane is 0,8,1 and my jungle is 0,4,0 because he tried to help toplane.
I´ve seen enemy midlaners hit 9 kills in 9 minutes, 14 in 15 minutes and 23 in 19.
I´ve gotten fatter than jabba the hut and just rolled over the enemy team a few times myself too, before having another game were i am 0,4,1 in 10 minutes because i screwed up somehow......usually not respecting the enemy junglers enough in my case.
Anyone and anything can start handing out their lives like free soup at a street kitchen at anytime, all you can do is hope its not you or your teammates.
