User blog comment:TheTobarMethod/ADC Mid....It can work!/@comment-99.229.45.199-20130129011903

There's 2 really big problems with this, imo:

1. ADC and support are the roles that scale the least with levels, so it makes sense to put them together so they can share exp. If you put any other combination in a lane together (AP mage, top bruiser, etc), at least one person will suffer from lack of gold and exp.

2. Being mid means being able to roam and help out top, bot, dragon, jungle fights at blue and red, easy access to blue, etc. Early game, an AP mage provides so much for the team in a 2v2 or 3v3 fight with their huge burst and cc, while an adc provides a lot less. The adc can't gank at all, so putting him mid is a bad idea. A final point, if the AP mage was bot, he might have to walk almsot all the way across the map just to get blue, which sucks.
