In the last two games I've played (which have been my MOST successful on HARD level), I have created ONLY YS, YA, SA, and WM (maybe a few No-Dachi). No Naginata, no ninjas, no Cavalry at all. Strangely, it seems to work fantastically.

(Note: I only play SP, so this wouldn't work in MP)

When the enemy has a bunch of cavalry, they die like roaches upon my Yari spears.

The only two difficult areas are:
1) Lots of archers
2) Lots of Yari Samurai

The archers problem is solved with a sprint (usually uphill) in LOOSE formation, ending with a CLOSE formation right as we collide.

The Samurai problem is only solved with good flanking and a few scattered MONKS.

It's working pretty well for me... (Note, I also make Shinobi by the millions).

Anyone else do a similar type of selective production?
