What makes them annoying?
The hit detection in WT is superb. I’ve dodged torpedoes with less than a metre of space. Some of the larger ships can actually take multiple torp strikes if you manage to keep them hitting the same space and that space doesn’t hold anything explosive.
You get a warning for incoming torpedoes when they are close enough, giving you between 400-500m warning as they approach. Some boats can manoeuvre quickly to dodge them, but it is difficult with others. It also depends on what the travel direction they have relative to your ship.
I’d upload some video, but it takes so fucking long for me to upload anything from here
