I really like the new balances in LH.  I played a few games and here are some issues I had.

1. Ascian (the panther hero) was not controllable normally.  After I used the collar and captured him, I had to select each portrait in the army to be able to move the army.  When I removed Ascian from the army, I couldn't move him until I added a second unit.

2.  The Curgen's Tomb monster area would not clear, all beasties/Storm Dragon were killed and treasures taken, but the green outline remained and the area was dead to me.
