A few thoughts on the game so far:

*  In the lvl 5 city bonus options Onyx Throne is not buildable even though it is an option.

* Champions, exp sharing between Champions and Sovereign seems to be not to have been thought out all that well.  As it currently stands your choices are to lvl your sovereign quickly or to group with champion(s) and lvl him and the champions slowly.  As a result I hfind I'm not making any use of the champions except as city guards or for spirit rip for talents.  In my opinion the exp sharing should probably be reset back to the .77 model, where exp is awarded without dividing a specific amount between soveriegn and champions.

* Boats.  Please bring back boats, that was one of the more entertaining elements in WoM.  I know they where removed for a reason, but I'm sure they can be successfully implemented some hout.  One suggestion is to take a page from Master of Magic, and have several different classes of ships, perhaps a transport ship, a light, medium, and  Heavy attack ship.  with warships is should be possible to customize armor and weapon choices just as it is with ground troops.

* Imperium quest seems to be broken at the moment, or at least I've never been able to successfully complete it. 

* A problem that I did note the other day was that if you use an escape scroll to leave the Pyre of Man battle the battle resets to base elements and you loose the chance to defeat the boss.

Overall so far I like what I see, everything seems to be heading in the proper direction.  I look forward to seeing what you have in store for us in the future.  Keep up the great work.
