Walls Shouldn't Block Torpedos

They also shouldn't have as much health... but that's a different topic.

I concur. There's no logical reason for walls blocking torpedoes.

Don't the walls stretch underwater too?

Because they should.

Then they need to be re-modeled.

There is a torpedo net under walls

I'd be fine with that.

I didn't see the walls blocking torpedoes. At least, Gunshin's (?) Commander was still getting hit by torpedoes despite his wall, possibly because the Commander is deep in the water and torpedo launchers are on the surface. In any case, if the torpedoes are getting blocked, it's because they were hitting the walls.

Why the hell would walls float on top of the water?

Doesn't the model for the wall reach down to the sea floor? It should block torpedoes.

The walls didn't stop torpedos. I was carefully checking that during that game
