Thank you for posting this issue here. It is definitely a lot better than Facebook for keeping a rule discussion like this going.
ok, I would like to start my opinion with the fact that I have never paid any attention to this spell before as vampire counts are WAY to rare and then no one I know even has the tomb kings. So this is literally my first time studying the spell text and rules.
As I do that, I see one thing that jumps out at me. The rules state that it is cast on any 1 single combat engagement, so if you raise dead behind your enemy in 2 lines for revolution......1 supporting the other 3 stands wide....I think its safe to assume it must still be 1 engagement and your hits count as such. In which case, nothing changes from vanilla to revolution, if you just keep assuming the 4 lines of combat..... enemy, friendly support, friendly, enemy.....is all 1 engagement.
I will agree, if you split it up into 2 engagements and count hits that way, the spell is really awesome and will win the combat for you almost everytime. But as 1 engagement with all hits pooling together, I think its still a fair enough fight, the spell is still advantageous but not overly so.
I'm for just giving the spell a slight re-wording to keep the engagement as 1 single engagement, and you must deploy the raised dead unit in a way that keeps it a single engagement as it was at the start of the shooting phase.
But, I might still be missing something because this is my first time reading these rules.
