Sorry but this is not my kind of game at all. Maybe I will grow to love it 
The armies look like a big mess of "blob" with no real tactics other than what your heroe is armed with.
Total War LOTR mod will do me.
Never been a heroes kinda guy so I guess the targetted audience is very different to sins.. reminds me of that other game by star dock called elemental or the original warcraft2 or 3 with heroes thrown in.
If you brought the game to a little more contemporary status I would recommend spawning foot soldiers as solid units rather than individuals, so they look like armies. Remember the game praetorians by that spanish mob, that was a lot of fun and spawned units.
