In TW games one thing I really like is total control. Some small things are ok, such as the command delay, but I wouldn't enjoy it half as much if it took some derivation of hands-off approach. I loathe the games that take the "operational" point of view, and just let you issue some general commands to your troops after which you can only watch the battle unfold.
And wall battles take forever and are not really interesting because 1) only one unit of each side is fighting, the rest sit and wait; and 2) not much is going on in general since only two units (out of say 20) are fighting. Having the AI rout on contact in 95% of the open-field battles is however not fun for me.
