1) Do you think there'll actually be three versions of the card (two of which they've hidden), one for each slot (but with the same name, so you can only have one per shop due to Limited)?
2) Is this really just meant as a bomb fix, and a torpedo fix will come separately?
If neither is true, then it's done bugger all for torpedoes on ships that can only take one (and not much on ships that can take two).
