User blog comment:Odisseas25/Why does the AP go to mid?/@comment-74.14.12.61-20130210002515

You could theoretically throw an AP bottom lane with the support, a support such as Soraka would be monstrously beneficial to an AP, and have the AD go mid to farm. This would pressure a lot of bottom lanes very hard early on as AP's scale very well with levels, and if the AP is paired with Soraka then the need for Blue would be almost non-existant freeing it up for the jungler should they use it better, like Amumu. However, as stated already in the comments, another reason that AP's are thrown in the middle lane is so they can roam to both the top and middle lanes quite easily for ganks, as most AP's burst damage is great for ganking. Like I said, you could easily pair an AP with the support, but the meta as it is right now is the way it is for good reasons, this however does not mean that you cannot innovate with great success.
