User blog comment:TheTobarMethod/Why is Mid one-sided?/@comment-3974211-20130319192203

Mage as a role is intended to kill the enemy mage/carry - so most mages excel at killing other mages. The exceptions are usually the mages that excel at not dying to the other mages, such as Swain and Morgana. Some mids scale too fast and one death can lose you the game, but I ultimate find mid the funnest. It's the closest lane to Dominion (the game mode where dying is only punished through lack of presence - it doesn't punish by directly rewarding the enemy).

From my perspective, mids only suck when it's a high roamer versus someone who cannot roam. This is when it becomes one-sided... and usually because your team mates die, and not because you die.

There are some hard counters, but that is true for all roles. Personally, I think top is the worst - simply because most tops are melee and typically can't clear fast. If your enemy beats you, there is no coming back - whereas mids can still safely farm, and your enemy is unlikely to build defensively with their spoils, meaning they are still easily killed.
