Yes, I believe I pointed that out, my point is that archers of one clan is stronger than the other because of a stat boost, while in other total war games it makes more sense that a Bretonian longbowman is stronger than a Saxon archer, because his bow has almost the same length as it's wielder's height.
I even tried to spot a slight difference that might occur between a superior Date no-dachi warrior and a generic equivalent, but no, the only thing that sets them apart is the flag that is apparently sticking out of their spine.
It's not that I am asking for a lot of eye candy, but to compare it to other games, imagine if in a shooter instead of one army using M-16 against another using Ak-47, both would use AK-47, but one army cleaned them better, so they have a slightly better range.
PS: Siege weapons? So far my troops are climbing those walls with a better proficiency than monkeys, why would anyone need siege weapons

The Imjin War would make a good expansion, but it's unlikely to happen due to the publisher's stance (SEGA doesn't seem enthusiastic about a war between Korea and Japan—I rather doubt that Koreans would care, but who knows). I'd love a Three Kingdoms expansion that did away with Japan entirely (most of what would be needed for this is already in the game), mostly because CA will never make a game based on the era, so the only hope is some form of expansion.
I'd love to see 3 kingdoms setting. I also believe there is more room for troop diversity in that setting.
EDIT:
Oh I almost forgot to mention one thing that has always been excellent in all Total War games. Music. I noticed it at once in Shogun 2, I don't know how Jeff van Dyck does it, but he always makes music very fitting for the set atmosphere in the game. Even after not playing some of the games for several years, I still remember the awesome soundtracks from them.
