Focus: An Essential Tool for Any Teamfight

When playing games, one of the big things people seem to struggle with is who ti focus in a teamfight. It's a natural reaction to go for the squishiest target first, such a support like Sona or Soraka, however the support is usually the last person to go for, apart from a pure tank. To make it easy, there is one rule everyone should follow. "Kill or CC the champion that does the most damage." The type of champion that is doing the most damage usually changes throughout the game, as well as depends on who won their lane or not. However there is a general layout if your lanes come out close to even.

• Early Game - During most early game engagements, the AP carry will do significant damage compared to most other carries. They also normally have a good CC so it's always good to get them out of the way first.
• Middle Game - Middle Game usually the AP Carry is still the main target unless the ADC has has extremely good farm. This isn't to say ADC don't do anything, because the middle game is when they begin to get good damage. However an AP Carry will still do more damage with the level advantage, and most likely has some AOE ability.
• Late game - This is when ADCs shine the most, and will usually make or break a team. By late game, ADCs usually have a few main items and really punch a hole in anything that moves. They should be the first to die in a team fight and should be the main target for CC.

These generalizations are assuming that your lanes were pretty equal, and no one was extremely fed. In the case of a very fed champion, always focus and CC him. When it comes to early or mid game fed champions, it usually means that he took the majority of the kills and left his team underfed. A well rounded team will beat out a team with a fed champion any day, it just takes patience and communication.
