An advantage I hate (Mid lane mostly but sometimes top)
Just by picking an AD laner against an AP laner the AP laner can't roam without you killing half their tower. But since they're AP you can roam all you want while they kill your tower at a snail's pace. So even if you're losing and they're carrying if they decide to roam you could come out on top just because you can kill a tower and they can't.
I need to start playing AD assassins like this is a really annoying reason to lose.
