Why AD mid laners suffer in queue
Im a midlaner that plays mostly AD assasins because they are my favorite and more fun to play, every queue its a nightmare because AD mid laners require a good team comp to be at their most effective unlike AP champions that work in every comp because you are guaranteed an AD source of damage (ADC)
Like any AD mid laner you need a source of AP damage coming from another player be it top,jungle or support (wich is the worst option). Well thats the trick, alot of people other than mid lane are not willing to play AP champions and its almost as you are obligated to play an AP champion because you play mid.
AP mid laners do not suffer this at all, in fact they can pick any of the many AP champions not taking any consideration to team comp because it realy doesnt matter much. If you are willing to play an AD midlaner you have to pray your top laner or jungle play an AP champion and it almost never happens, and who can blame them because for top and jungle most AP champions ment for that role suck ass or boring farm champions like swain and vladimir, there is no AP riven like champion that can make top laners play more AP
