Based on Frogboy's latest post as well as the original posts (including the FAQ), here is what we know about LH:

1. The beta may start this week.

2. The hero recuitment system will change from them being placed on the map to the heroes approaching you based on fame.  A few will be the result of quests.

3. The champion progression system will change.

4. Shadow effects have been implemented.

5. New tactical combat options:  swarm, closer initial placement.

6. New monster types.  Two:  Banshee and Garagox were mentioned.

7. New spells and abilities.   Wall of fire, Raise skeletal horde, wraith touch, rush were all mentioned.

8. A new scenario.

9. Other graphics changes (in addition to shadow effects).

10. Non human champions. 

Two questions:

A. Other players, what did I miss in the above?

B. Stardock, are there other changes you could tell us about in LH while we wait?
