Already in Sub Command, ASROCS where very easy to evade (died once in around 200 games by ASROC kill, due to poor maneuvering).
But I think the potential of those weapons is huge:
1. You get your opponent seriously busy on evasion in a very quick manner
2. You got the ability for example to cut out the escaping way of a sub
3. Easy to deploy
4. Fire & Forget
Drawbkacks:
1. You give away your exact position in case there's someone above the surface
2. The torpedoes attached to the rocket really suck (in game)
about point two I don't understand. Why don't fire an adcap with a rocket?
About wire guidance... I could imagine a system where you wire guide the torp without the wire... sending frequencies trought the water medium, why not?
