Ok, some of these are better, but I still have some issues.
There's a HUGE jump from Pikemen to Musketmen. Ouch. Lower the musketman attack by lots, and the defense, maybe a point or two. Otherwise, knights n such will be useless! I still don't really like your choice with the war elephant, but i can get over that.
Another thing: lower the attack of Infantry. They aren't really an attack unit... as mentioned, they are for defense n such.
AEGIS Cruiser: lower the attack, possible the defense. battleships are the biggest attacking ship, and should stay that way. AEGIS Cruisers aren't meant to replace battleships, just supplement them.
And lower the defense of privateers a lil.. don't want them to be too hard to get rid of....
Rest looks pretty good.
