I have to congratulate stardock on a an incredibly stable release.
That being said here are a few of my observations based on my recent game.
1. Tactical Battles
All in all a very satifactory experience how ever a few interface changes could be in order...
This character is plagued... What does that mean? A way to see what attributes are effecting a character and what those attributes are doing.
How can I tell what element the opponent is aligned with (in this case it obvious, sometimes it's not).
2. AI
The ai is already very competent however a it's far from smart.
Weak sovereign exploring my northern border while I'm at war with them.

A horde of dragons burst forth, defeat all my defences and when I'm at their mercy they... sit. This gives me plenty of time to rebuild my forces.

3. Interface

I can train forest drakes, YAY... what are forest drakes? Maybe a link in the entry of the improvement to the unit it enables. (ie, a link from forest drake lair to forest drake.)
4. Wildlands
I cleared a wildlands of evil nastiness grabed the loot but couldn't settle in there. Is that a feature, bug, lack of information.
5. Bugs
Here a few bugs I noticed.
1. The 'Assassins Blade' quest would not complete.
2. Scouts wouldn't auto explore.
3. Load won't load. I'd provide the save file but I can't find it.
That's about it for now. There was more I wanted to say but i forget now (need to take better notes).
Great job so far guys, already way better then WOM.
