I feel bad for top mains
I put top sometimes as a secondary role and get stuck playing up there and I always am the first or second pick. If I pick any melee the other team goes teemo or quinn top and i sit under tower not playing or take infinite harass. That has to be the worst position to play unless you are the one counterpicking.
and 
sustaining everything,
burning you to half hp in 2 seconds,
early game is easier to deal with,
). Hell,
first item stops any ap top laner. So all you have to worry about is melee and the occasional adc top (
like this broken basta-)
I don't see the issue.
