Combat Rating (abbreviated CR) is a statistic possessed by player characters representing the overall power of their equipment. Combat rating is calculated by averaging the item levels of all of a player's equipped items. Update 6 made this statistic visible to players through the statistics tab in the inventory screen. Update 6 also introduced combat rating requirements on some endgame alerts, duos and raids, preventing players from queuing for these instances unless they had a sufficiently high combat rating.
Until 2013 the combat rating was considered a PvE only statistic since unmodded PvP gear never had an item level higher than 30. Game update 25 then introduced a PvP item level and now every player has a Combat Rating and a PvP Combat Rating.
It should be noted that items players could not use due to lack of DLC packs do count towards combat rating.
Equipment Mods only affect PvE item level. While they can increase the stats of PvP gear, they have no effect on PvP item level or PvP combat rating.
Each Item is weighted with a coefficient, so it is not just counting all values and dividing by 14. A user approximated the equation in the SOE Forum and it goes like this:
(1.4We + 1.5He + 0.7Ne + 0.95Ba + 1.75Ch + 1.75Le + 0.5Ri1 + 0.7Tr + 0.7Fa + 1.3Sh + 1Ha + 1Wa + 1Fe + 0.5Ri2) / 14
- We = Weapon
- He = Head
- Ne = Neck
- Ba = Back
- Ch = Chest
- Le = Legs
- Ri1 = Ring 1
- Tr = Trinket
- Fa = Face
- Sh = Shoulders
- Ha = Hands
- Wa = Waist
- Fe = Feet
- Ri2 = Ring 2
In order to raise your CR level faster, get your high level gear in the following order:
- Hands and/or Waist and/or Feet
- Neck and/or Trinket and/or Face
