Cap

From WoWWiki

Cap, soft cap, or capture can refer to several different things depending on the context.

Relative to battlegrounds or world PvP, "cap" may be short for "capture," the capturing of an objective or object, such as a graveyard, flag, or tower. Many of these objectives require being physically held, such as a flag, or maintained dominance, in the case of a tower.

"Cap" may also refer to the level cap, or the highest level that can be currently obtained. During the release of World of Warcraft, the level cap was 60. The level cap has been raised for each successive expansion.

Finally, "cap" or sometimes "soft cap" may be used when referring to gear itemization. For example, players theorycraft about the hit cap, the expertise cap, the dodge cap, the spell penetration cap, and others. Some stats do not have any cap, while others have a soft cap because of diminishing returns, as in, additional points of the particular stat realize very little if any benefit after a certain amount.
