Now, part of this strategy is crafting how your team will play. In many instances, a team will have a standout player or two. In this situation is it logical to want to get them ahead so they can snowball the game. If you have Faker on your team, it would be strategically dumb not to commit extra resources to the mid lane. Now, the usual way of getting a lane snowballing is by help of the jungle. The second way is to funnel more farm to them. In the example of SK Telecom, Faker not only has Bengi camping his lane, but is also funneled more farm than any other team member. Both of these techniques to snowball use the finite resources of jungle pressure and farm.
With jungle pressure, it is more realistic for a jungler to gank two adjacent lanes. The reality is that a jungler can not camp three lanes and be as impactful as a jungler that camps two. Summoners Rift is a lengthy map, in that it takes a while to get from top lane to bottom lane. Because of this, the jungler is a lot more efficient if he ganks adjacent lanes than if he ganks top and bottom. This leads to teams prioritizing either their solo lanes (mid and top) or mid and bottom lane. In the case of OMG, Cool and Gogoing have been the main prioritization of jungle pressure. In the case of Samsung White, Pawn and Imp were the main priority. Rarely, in a team who was considered the best in the world at any time, has top and bottom been the two carry lane. In WE, it was Misaya and WeiXiao. In Samsung White, it was Imp and Pawn. In Samsung Blue, it was Dade and Deft. In SK Telecom, it was Faker and Piglet. Even in Moscow 5, it was Alex Ich and Genja (I know it hurts me too). These factors lead to one lane not getting as many ganks.
With farm, only a finite amount of minions have been spawned at any point in the game. Because of this, if facing a worthy opponent, it is almost impossible to have all three lanes equally farmed. When a team rotates, one lane, usually the most fed lane, gets funneled most of that farm. On top of this. if you have more ganks, you can farm easier. A player is just more likely to get funneled farm on rotations if they have been the priority of the jungle pressure.
The way the game of League if designed, one lane is going to have to take the hit. One lane will have less jungle ganks, and because of this, less farm. It is a fact, and one that is backed up with historical data. Because of this, players like Flame, Faker, and UZI would not work. These are three players who have commanded huge amounts of jungle pressure (Helios for Flame and Bengi for Faker) and massive amounts of farm (I mean come on, just look at the any world championship game with UZI in it.) One of these players would have to play a more supportive role.
