Personally, I liked Torpedo High Yield until I got a plasma torpedo launcher during open Beta. However, now that I am in head start... my Tactical Officer has Torpedo Spread and I'm not sure how effective it is so far. Sometimes it looks like it's pretty powerful, and other times it seems like the spread is all over the place. I've already leveled the Spread to level 3, and I'm afraid if I ditch it for High Yield now... I'll lose those points I already put into it.
Does Torpedo Spread get better as you level it up and is it really that effective?
