I forgot to mention that the "suicidal daimyo" is still present. The AI will do it with friendly reinforcement armies if they are led by family members.

Javelins seem to have improved a bit in their role, although they still take quite a bit of management.

Friendly fire is overdone. Men in the same unit will shoot each other. (This happened some in STW.) If you leave fire at will on they will kill a bunch of your other units in melee. If you turn fire at will off to stop this, you must issue a "halt" command as well, or they keep on merrily shooting everyone.
