Matchmaking MM Each ship has a certain combat tier assigned to it. It determines the maximum level of enemy and ally ships that can be encountered in the battle. The information below is current as of patch 0. Example: If two Soviet Gnevny destroyers and two Japanese Minekaze destroyers are present, the matchmaker will attempt to put one destroyer of each nation on each team. Divisions Divisions of up to three ships can be created. Currently divisions can only have one carrier and a random team can have no more than two Carriers. As of patch 0. A division with a Tier VI ship, for example, could include ships of Tier V and Tier VI, or Tier VI and Tier VII. Tier V, VI, and VII ships are not allowed in the same division at the same time. When placing divisions in a match, Match Maker will only consider the highest tier ship's Match Making tier range for purposes of tier placement. When divisioned with ships of the same tier, the division will see the normal Match Making for that tier. For example, a division of only Tier 5s will only see matches with Tier 4 to Tier 7 ships. A division of only Tier 6s will only see matches with ships from Tier 5 to Tier 8. However, when a division is made up of ships of unequal tier, only the top tier ship's tier range will be considered. Thus, let us say the Tier 5 and Tier 6 above form a division. Match Maker will only consider the Tier 6's tier spread. The Tier 6 can see Tier 8 matches, so the Tier 5 in the division with it will now also be subject to seeing Tier 8 matches where it normally would only be able to see Tier 7s max. Ship Performance Factors For each ship there are seven performance factors that provide a basis for comparison of any one ship against another in game. These performance factors are expressed on a relative scale of 0 worst to 100 best. Each performance factor is based on the ship's abilities. Note that these factors are just a basis for comparison, and can change based on what modules, upgrades, or captain skills the ship is equipped with. Its mainly all about hit points. The T10 BB's IJN , KMS , HMS , USS and MN share top Survivability factor in-game with 100. Many tier one ships share the worst, with 4. The main battery firing range in kilometers and the number, type, and positions of the main battery and the secondary armament guns contribute to this factor. The US T10 BB , IJN and UK T10 BB have the top Artillery factor in-game of 94. Asides tier 1 ships, The IJN T2 DD has the worst with 2. The number and caliber of the on-board AA guns contribute to this factor. S T10 CL has the best AA Guns factor in-game of 96. Many ships, such as the US premium T4 BB , IJN premium T2 DD , Russian premium CA and KM T3 BB A hull have the worst - 0 - because they are not armed with any AA Guns. The IJN T5 DD and Russian T5 DD share the best Maneuverability factor in-game - 95. The US T4 CV has the worst at 7. The IJN T2 DD and it's T10 cousin has the best Concealment factor in-game of 98. The US T10 CV has the worst at 5. Many camouflages, such as the Type-1 Camouflage further reduces the detectability range by sea of the ship it is mounted on by 3%. The number, type, and position of the torpedo tubes and the range of the torpedoes contribute to this factor. The IJN T10 DD has the best Torpedo factor in-game of 60. The IJN T2 DDs and , as well as the USS have the worst rating which is 4. Those ships not armed with torpedoes have no Torpedo factor. The total number of squadrons, number of planes, and the type and capabilities of each of the planes: fighter, dive-bomber, or torpedo-planes; determine the Aircraft factor. The USA T10 CV has the best in-game Aircraft factor of 86. Battleships can only mount catapult fighters at tier 7 and up, with the exception of. Only CVs have an Aircraft factor.
