If you think WoD needs to run a bit more like D&D this is your book. While the combat options are decent, they are a bit clunky so expect to spend a fair bit of time, characters points and effort in combat if you want to include this module. WoD:Combat is well written dropping the RP fluff and getting right down to combat details to give you most you can get out of an RPG book but it mostly feels unnecessary for WoD so I'm not sure you will get your money's worth out of it as I can't see using these combat rules with very many stories.
Exalted or D&D are much better suited to more battle heavy games with volumes of combat oriented material written for them. While WoD:Combat does add a bit of spice with new combat abilities and more detailed mechanics it still pales in comparison to games built around combat. I think for most people added extra combat rules to the World of Darkness will feel unnecessary as that isn't really what WoD is all about it. I'd wait for this one to go on sale if you really want the extra combat options with the exception if you are planning on playing Demon Hunter X which I feel will benefit most from WoD:Combat.
