Ranked setup

This is a quick overview of lane position setups in a normal ranked game. In depth explantation will be coming shortly of each individual position explaining exactly what their goal is, and how they interact within the team. A normal ranked 5v5 game will consist of:

• 1 top laner, normally a tanky bruiser type of champion. (Example: Shen, Singed, Jax) Champions with high mobility such as Shen's ultimate, or taking Teleport as a summoner skill are often very successful top laners because it allows them access to the rest of the map instantly, rather than having to walk down to a team fight from their lane. It allows quick coordination of dragon attempts, split pushing then rejoining the team, and even suprise ward teleport ganks.
• 1 mid laner, usually a bursty ap (sometimes ad, e.g. zed, khazix) with some kind of crowd control ability. Mid champions focus on sustainability in lane as experience is extremely valuable to them, as each level of their abilities add more damage, longer durations, and sometimes lower cooldowns. Good examples of mid laners would be, Lissandra, Annie, Khazix.
• 1 jungle, this position can vary as it is based on your team synergy and play style. Popular jungles usually have some kind of crowd control, whether it's a slow, or a hard stun. Most junglers need a slow or stun in order to gank lanes successfully, however sometimes a simple gap closer can be enough. Examples of a burst damage jungler would be: Shaco, Evelynn, or Xin Zhao. An example of a more tanky, and crowd control centered champion would be : Maokai, Vi, or Sejuani
• 2 bottom laners, this is usually made up of a support and an ad ranged carry. There's a few select ad carries. Graves, Vayne, and Caitlyn to name a few. Their main job is to maintain bottom lane and farm (or kill) as many creeps as possible in order to accumulate gold for later in the game. Ad carries gain most of their damage through items that effect their auto attack; attack damage, attack speed, and critical chance. Supports are there to provide sustain to their ad carry so that they will maximize their time in lane and farm as many minions as possible. There are a wide variety of support champions as well. Some focus on mitigating or preventing damage, while others specialize in healing damage that was dealt. Examples of supports that mitigate damage would include Janna, Thresh, or Leona. Supports that assist through healing include: Soraka, Taric, or Nami.

This is a very general overview or the lanes, and there are always exceptions to the rules, or champions that can fill roles simultaneously. This is not to be taken as set in stone rules, this is just a overall view of what a 'regular' game might look like. I will be going in-depths into each role in the future, to explain exactly what its goal is, and how it is achieved.
