How do you use standard generals?

[tinkthank]

I notice that no matter what nation I play, I tend to get casters or at least those commanders who have some special ability. I almost never get the "Emerald Lord / Machaka Chief / Traitor Prince / etc. type" -- what about you?

Basically, I only get the other types if I am in desperate need of a quick commander; I feel that the slightly lower costs hardly justify me to spend that turn's commander recruitment on a person who can hopefully avoid arrows. Aside from being very helpful in battle, a mage can at the very least do some research and some forging, a priest can build a temple or preach, a scout can give me information, etc. -- but what can a general do besides ferry troops around and die? This is not an ironic question. I feel I am missing something.
