Yes, fewer cruisers/battleships, more fighters/gunboats. One problem that I've seen is that there are more battleships available than cruisers and gunboats COMBINED, not to mention the lack of bombers. Next mod version should help with that a bit.
I don't see a reason to limit Mk2 fighters... Many NPCs are pretty darn tough to take out without the best equipment a fighter can get. Especially with light fighters. Heck, even a Mk2 light fighter still has a lot of trouble.
I made a suggest in another thread to limit battleships to faction-only, and limit each faction to one battleship and one cruiser per five members. Unlimited fighters and gunboats. If a faction is going to war and wants more cruisers, hire a mercenary. If they want more battleships... Find an ally willing to break out their flagship.
Has anyone read the Kusari news bit about them sending five battleships against Bretonia, five? Like five is supposed to be such a great amount? That's nothing.
