Hmm, is it just me or are the forums lagging horrifically right now. Anyway.
The unrest thing is slightly weird, I had unrest in my capital when all I was doing was producing ork prentices there, no heroes, and other than that just 80 odd orc troops sitting in the garrison. The orcs do kill things well enough in melee, I just find it's the getting there that's hard. Against someone with a lot of ranged weapons I have to send 3+ large groups of melee orcs or they never reach the shooters due to morale issues. Of course I'd probably have less of such if I used the standards on heroes but they're too fragile and too important to use aggressively without items.
If power blasters are getting such a boost, I would like to see other units have stronger blasters, like siege tanks (which use a standard issue space marine blaster)
A new map would take a lot of work, that's really more of a wishlist feature... would be nice but isn't necessary. Something else along those lines: I've noticed ulm's black knights seem to have a sort of black graphical bit that sort of floats behind the sprite. They lose it in their attacking form, but it makes them look a bit odd when they're at rest.
