I would love to see all those things implemented. I'm aware that there is a lot involved and that if it happens, it won't be for a long time.
This is the "wishlist" forum, and the "wish" was for LST's. I'm all for these too.
My argument was that the current state of carrier ops isn't exactly historically accurate, therefore it is a moot point to call out the accuracy of putting a German tank on an American landing craft. (Actually, it's ALL moot as we don't have said craft.)
If everything that you suggested as far as different fleets for different countries was implemented, then I could see the validity of the "no Tiger" argument. I'd still +1 the LST, due to the fact that American iron could get the job done just as easily. This begs a whole new question.
Did the Axis forces have a similar piece of equipment?
