Nice report!
One very minor quibble though - you
can move through (though not charge through) friendly units - so the undead could have gotten themselves out of the box that they had put themselves in. (This can be combined with Surge in entertaining ways....)
The thing that my group noticed first is how fast the game is when compared to Warhammer - we get in two games for every one game that we used to get for Warhammer
Which has led to us playing four times the games, because we are more willing to fit in another night when we know we will be getting in more games. (We also have a monthly Drunken Kings game... Kings of War as a drinking game... my good lady's idea.

)
