This topic was again brought forth in a PBEM game I'm playing right now.
As the Axis, I decided to do a SeaLion after finishing off Alexandria. I felt absolutely no inclination to send my ships into harm's way to intercept, block or assist the landing. Maybe there would be a use for them against the USA, but not in a SeaLion under the current system. I've always thought a naval zone system works best with strategic games, if you can handle the abstraction, and it has been confirmed again. Clash of Steel got it right in at least that regard. Whatever solution is reached, I am glad that so many others agree that there is a problem. I look forward to whatever Hubert comes up with as a fix.
Other than that small problem, this is a very fun game. Definitely worth the $$.
