Trading commanders, exploit or not?

[Psycho]

I wouldn't consider it an exploit. It is merely a different kind of trading after all.

The ankh thing, now when I have some experience with it, I would definitively consider an exploit. Maerlande and Ink, the ankh trick is not about saving your commanders, but about cheaply raising tons of undead. OTOH, Lanka, for example, once the research is done, can do the same with regular commanders, so against them maybe it's justified. I would like to see the ability removed from demons.

The sickle farming was not such a big deal with gem gens. Without them I think it should be banned from games.
