I didnt realize I was quoting YOU. I thought others had said it also. If its jsut you saying it then... well there would be no need to comment on it.
But when I say Ulm players I refer to the style, not so much the nation. The armored armies sweeping forward meeting armored armies style of play. As opposed to playing bless, or stealth, or defense, or research, or any other thing that a nation seems perfectly setup to do. Forcing a nation to compare to Ulm style combat tends to make many of the nations "suck".
As for the aquatic rush, they only have to take one province. After that the fact that I have magic/priests is adequate. I can use the locals to expand in water from there. As a land nation they actually have quite an advantage in water.
