Its fair to say I am new to Wows, I've played probably around 400-500 games in total. remember cruisers can use Torpedoes as well - as well as the Scharnhorst which is in my port too.
Evidently their is a potent learning curve when using torpedoes. however its extremely likely that griefers on a game like this will deliberately drive into the path of friendly torpedoes to force team damage.. you know it and i know it...
