User blog comment:TheTobarMethod/ADC Mid....It can work!/@comment-4131177-20130128215128

There are several things that basically make it not viable to go mid as an AD carry compared to sending an AP carry mid.

First you have to accept that the AD carry's job lategame is to be a major source of sustained damage. More than jungler and top, and more than AP carry. When we're still on the same level, keep reading.

That you want to maximize your damage means that you need to invest every pence you get into your equip. Now, in mid, to be safe, you need warding. I know that, unless you are in ranked or playing with really good players, noone except the support touches wards, but they should. And in higher level of play, warding is necessary. This means, if you want to put the AD carry mid, you have to put a support alongside of him to take the ward burden from him so he can invest the money into getting stronger instead. In result this means that you have to put the AP carry either top or bot. The fact that the outer turrets have far more distance between them means that you need much longer to get from the middle of the lane into safety (about double the time). Thats bad news for a squishy AP that just got ganked by a skarner. Sending the support to bottom would not work because mid needs the warding, and, since the AD-carries role is to carry the game, he also needs the maximum assistence he can get. I think you see the dilemma.

Additionally, most AD carries are countered by an AP carry in mid for the following reason. AD carries tend to deal much sustained damage, while AP casters tend to deal much burst damage. Now, imagine a two seconds damage trade. A caster can gladly unload his entire damage potential in 2 seconds of time, while an AD carry could get out 2-3 autoattacks, maybe one of them a crit if he/she is lucky, and a spell. So, if the caster now decides to only go for short trades, and then just go back into the safety of the extremely close tower after he is done unloading his spells, the AD carry will horribly loose all and every exchanges and can not focus on farming and thereby not fulfil his role.

This all is in regards to the current meta (ap carry mid, ad+support bot, bruiser top, jungler). But as you already found out, the meta is shifting right now (due to its nature, i mean, in the end thats what meta means, "evolving state of play"). I am not sure that bruiser mid will actually establish, because bruisers are quite easily countered. A bruiser in mid can destroy certain AP carry mid lanes, but it is a specific counterpick, and far from a "jack of all trades" choice for mid.
