Some players level dupes into K2A because their performance is the best of the best, where in Events you don't have to worry about which CV to use due to Ship Locking if you have dupes to use for the separate Ship Lockings.

However there are also players who worry that these 3rd to 4th Prototype Flight Decks will be used for other Ships (Ex. Saratoga who got her Kai Ni announced in last year December via Interview with Tanaka), so they refrain from using the 3rd/4th copy.

There are players who think that a 5th copy will be given via a new quest once this happens because of the fact other players may think it's unfair if a new copy isn't given for this (considering the 3rd and 4th copy were given out as Event Rewards)
