Couldn't find a better place for this so I'll leave it here?
It's been the case for ages now, but updating some of the game's older 3d models would be brilliant. For example, Kagero and Gearing both have models and textures that are visibly worse than newer ships. It's especially noticeable with these ships as ships that are extremely similar (ie harekaze and yueyang) to these have been introduced recently - it does make me wish that ships that are either practically identical or share a lot of the same features could be brought up to standard with the brilliant quality of some of the newer ships in the game.
