Well...
Obviously I have many wishes for dominions III (not as an insult to II), but here is a short list containing some of them:
1. Being able to choose formations, so instead of a square getting bigger the more troops you put in the squad you would get a choice of square, diamond (a square tipped by 45 degrees), circle etc..
2. Improved unit order - just like a lot of other people say - I understand that you can't provide a highly elaborate plane and expect your braindead soldiers to understand it all and memorize it, but something more elaborate than "Attack" should obviously be an option. As well as increasing the 5 commands limit, you should add a "And repeat X action" command, so a commander can be instructed to cast the same spell repeatedly instead of resorting to an AI selected spell.
3. More spells - Obviously, there are many spells, only you can't use most of them, since because they aren't very good and some because you don't have the mages.
This applies mostly to strictly offensive spells (with two or three being actually effective) but there aren't always good summoning spells available as well.
Obviously this will be taken care of in dom III, I'd just like to say I'd appreciate some more offensive spells a la fireball.

Maybe I'll add some more later, I keep thinking of stuff and then forgeting...
