I've dug it up again and remember that you can sink enemy ships on some maps. I've tried a few times but it's a lot of work so my question is: Is it worth the effort?
Sure it removes a spawn point but unless you manage to take out all ships the bots will just spawn somewhere else.
So does it incur some significant ticket loss, to make it worth it?
Also this question is mainly aimed at single-player where I don't have X teammates to coordinate with...
