While there are practical limitations to the number of torps the player can effectively control the current game permits trawling. An analogy would be rod angling where the fisherman has several rods set up and lures out ready. If he spots any twitching he can concentrate on that rod. In practise he will only normaly need to manipulate one.

Effectively limiting the number (2-4) of WGs capable of beeing deployed would achieve greater reality and mirror the self-imposed constraint exhibited by experienced players in MP.
Fly fishing instead of 'bait-slinging' ?

The game playing limitation would be implemented in Weapons where for example the SW diver would be limited to 2-4 tubes capable of loading and controlling WGs. The other tubes would permit MK 48s running only in 'shoot and forget' mode. (apparently a 'real' option)

A real option but unfortunately beyond my powers of doctrine and database manipulation.

Sorry...
