Well it's good to know I'm one of the few Mid laners out there that isn't an asshat I guess. But every role has certain douchebags in it;
Junglers bitch at laners when they die invading with no vision, ADCs throw a tantrum and fall behind when you don't serve them kills on a silver platter because they have no idea how to farm, supports flip out when they die engaging even when you're at %20 health and can't help, Top laners whine they don't get ganks when they've constantly pushed the lane right under the enemy tower ect ect.
Whiny people whine and childish players act childish.
