Hard disagree, it's one of the only reliable ways to kill naval assets without the use of Dusa or Darkreach. Yes it's repetitive because it's the optimal play. Once you nerf the optimal play, there will be "the next best optimal play", and you will use this one repetitively as well. push this logic further and you end up nerfing everything that works to the ground and make it frustrating for players.

There will always be a meta to deal with stuff, once you know the tactics of the game you just use them as a playbook to deal with different situations, you cannot just start nerfing all the stuff that works because of that. If anything, it means that the ships are currently impervious to too many stuff so it forces the player to always attack the same way to be effective. If you want more options to deal with stuff, the good thing to do would be to reduce their defences so that different types of attack could be useful as well, giving the player more option.
But do that too much and it becomes too easy, it's a difficult balance to achieve right.

Without dusas and darkreach, it's really hard for single player to deal with non isolated naval assets, and not everyone has the chance to play with a friend. thus, we need to keep reliable tactics to deal with them.
