I wasn't really looking for a huge revamp and in fact like that it's a revision of DH1 to essentially 40kRPG 1.5 (OW). As a GM I have an easier time utilizing the hundreds of dollars of books I already have that at least have some level of compatibility with this system utilizing just a bit modification to fit. A new system would be more cumbersome for me to adapt.
In the end, game dynamics serve the story. A good GM needs to make sure the game system (and none of them are perfect) gets in the way of this. DH2 seems perfectly fine from that perspective.
This game obviously requires multiple wounds (hits) to take down even the lowliest of opponents. The Novice-class NPC requires 2 wounds to kill. I would argue that one of the beauties of 1st Ed was that most weapons (especially with righteous fury) could result in 1-hit kills. Not so here.
