USA declares war, turns up with a fleet outside the north-west of Germany, an invasion dot appears, I cant attack the fleet in that invasion, they are half of the force of required invasion force, and I loose half of Germany. Why is it impossible to engage a fleet that is in invasion mode?...

1900, China. Design and initial build strategy- three classes of DDs. One optimized for port defense / minelaying, one for general battle with torpedo / gun balance, one as a long range commerce raider with focus on range. Use one of the research flasks for better torpedoes, leave the rest alone (except to push turbines). Built 10 minelayers for each port, 40 commerce raiders, 200 general battle DDs as initial fleet. Adopt a generally defensive posture (not using 'increase tension', let the wars c...

seems like the last 3 campaigns i have tried after about 5 years of game play most of the countries have no boats just 20 or so submarines and lock themselves by trying to build too many ships at once, kind of kills the game.

Was using 2 modernized US standards against 1 Bismarck inspired battleship. The german ship had LVL2 radar, I had LVL3, both had the same stereo-optics, I had the experience advantage, they had 15" guns, I had 14" but with higher rate of fire and penetration, and for the most part the ships were fairly even in stats.

Versus Jeune ecole. Trying a 1900 A-H campaign building only battleships and a limited number of DDs purpose focused on minesweeping / antisubmarine / minelaying. 1.7 plain no mods. Initial economic setup was max transport growth, 25% crew training, 70% research, build shipyard (24 month so max there). Able to build 30 BBs and 36 of the purpose DDs for my starting fleet. Within 2-3 turns researched dreadnoughts, so started 2 under construction. Still OK on economy. Set the DDs to 'Defend' as soon ...
