What do you guys think? Taiyou also requires a protopult to get her to K2 if you have her, and I am willing to bet that Hyuuga K2 will have the same requirements as Ise...and as of right now there are only 3 protopults that are available through quests. They have been made available as event rewards in the past, but it's impossible to know when that will be a thing.

The Naganami-gun can at least be made (albeit very expensive in screws and time) and will, in all liklihood be standard equipment on other Yuugumo-class Destroyers.

My point is that you will need at least 1 more protopult in the future and there is no telling when they will show up again as any sort of reward, while the 12.7cm Twin D K2 gun can be acquired by other means.
