I'm in the early stages of a new game in 1.11 (I'll update to 1.12, but I didn't see it when I started this) and I'm noticing that a lot of foreign battleships...really have no business anywhere near a line of battle. They've got small guns, which might be forgivable, and also very thin armor that definitely isn't. At first I thought it was just the Austrian legacy fleet, where joke battleships might be expected (though the 9000 ton boats with 3x9" main armament are a shock even there) but Germany and the British are churning out their own contributions to the 'slow heavy cruiser' category.
Building battleships in 1905 that would be helpless victims pitted against the French legacy battle line (10" armor, 12" quality -1 guns) seems like a really strange choice for two of the big-budget powers.
I haven't encountered these things in battle, but I don't think the reports are too far wrong considering the piddling tonnages in play. The Monmouths are smaller than CAs that were in construction contemporaneously.
I can see much the issue that Michigan type small battleships with low freeboard are built by USA or UK even in late 10s. They have better main guns but still several thousands of tons smaller obsolete even at time of their design.
