Krieghund used to frequent this thread but he hasn’t posted for awhile. If you really want to know, you’ll need him.
In the meantime, I’ll take a stab.
I’m sure it has nothing to do with “game balance”. It’s not like it benefits one side more than the other.
It’s derived from the relatively new “ignore submarines and transports” rules.
Sure, they could have worded the exception to say “to avoid combat”, but they didn’t. My guess is, it is an unintended “loophole”, as I think also is the cheesy ANZAC declare war on Japan after UK moves a destroyer smack into Japan’s main transport fleet. IMO this is a much bigger scofflaw than your little sub thing. :-)
I’ll tell you a rule that bugs me more - it’s that you can’t destroy transports and also bombard from the same zone. If you have a single non-bombarding attacking unit, it should be able to sink the transports - you shouldn’t have to choose (whether to bombard, or to sink transports).
Seems you are extra focused on this one rule because it worked against you once in a game :roll:
My point is, as I said before, there are actually many of these quirky rules that could really bug a player. The rule book is set at this point AFAIK. Since 2nd edition, it’s been pretty much time to accept the rules as they are and learn to play with them. It is fruitless to seek reasoning or campaign for change. That ship sailed, when Larry was actually getting (way too much) feedback from all the players between OOB and 2nd edition.
If you really have a beef (again, I think you are just frustrated because you couldn’t sink a sub and it convoyed you for maximum damage once), then you should message Larry directly, on his website. Maybe you will have an effect on a future game. I highly doubt it.
There are many, many subtle little rules like this one that can catch a player off guard. Be glad it wasn’t one that made you lose the game. That can happen.
Also, now that you know the rule, it shouldn’t catch you again, and you can exploit it yourself. That’s always been a part of playing A&A, from the beginning.
Happy gaming, Magic
