I have played World of Warship for 1 year.And some player and I find that,in high tier games,we seldom saw Aircraft Carriers(CV) in the matching.I know that when the tier of game become higher, CV will be harder to attack enemy. It may make some players give up to play CV in high tier game. However,as I see,this is not the only reason that make players give up.
On high tier ships,their anti-aircraft(AA) damage is enough for keep themselves and their teammate safe.This setting is reasonable but some players make the AA damage of their ships become very high by using upgrades and commander skills.I have tried to play CV in the public test server.Although,there is no problem with Cruisers(CA) and Battleships(BB) increase their AA damage,some AA damage is too high that all the planes will be shot down before they can throw bombs or torpedoes.Also,this kind of AA will build up a area that CV players may lose many or even all the planes while that ship can be undetected.
Sometime I also see destroyers(DD) use the same method.Some DD have high basic AA damage,such as Akizuki of Japan,Fletcher of USA and Grozovoi of USSR.This method is very suitable for them to shoot down planes and lucky only a few number of DD can have the terrible AA as I said before.However,a few days ago defensive AA fire consumables of USA DD and USSR DD has been increased to 4 time AA damage after consumables activated.Nearly higher than other ships using AA skill and upgrades.
Moreover,since ver. 0.6.3,"Alt"-attack has been removed form tier 4-5 CV to protect the ships which don't have enough AA to keep themselves safe.This is helpful for low tier ships but at the same time, Japanese CV will easily lose air supremacy when they are fighting with USA CV.This may reduce the number of Japanese CV player.
Finally,I would like to know that is this phenomenon is same as developers expected.If no,will they are going to have some improvement for CV players.
