My thoughts about this mod. (And apologies for my possibly not so good english).
I think it's a bit like hitbox skins in WoT, i mean in a way that it takes out (at least some) of the needed skill of knowing where to aim/shoot, and ( at least i think) thats one of the most important skills in ship combat, especially for longer ranges.
And unlike some have said i don't agree that it's something everyone will learn after a few games.
Id prefer players having to learn that themselves and i wish this mod would be banned but if it doesn't i guess i'll just have to wait and see what it does to gameplay when WoWs goes public and hoping it wouldn't ruin the game completely by making it just another game of point the reticle at end of the line, keep it there and click away, ofc there's still some RNG involved but i think you guys get the idea.
