Crowd control
Crowd control is a term used in MMORPGs and MOBA games to refer to the ability to limit the number of mobs actively fighting during an encounter. It can also refer to abilities that influence or prevent the abilities or actions of other character. Crowd control can be extremely powerful, controlling the possible outcomes of an encounter, as it forces opponents to use a smaller set of abilities/actions. Players use crowd control to create offense/defense ratio imbalances between themselves and their opponent; used properly, CC often renders an opponent nearly useless, allowing the CCer to use abilities/actions against an opponent without fear of retaliation or response. In a group setting, crowd control often makes combat safer, easier, or viable.
