Hey guys so small question, Me and a group of guys are getting back/(after 8 year leave) to warhammer 40k and I purchased dark vengeance and in order to compare army values with my friends current armies I added up the totals of all the units for chaos space marines and dark angels (using their codex's) and it seems with only the contents in the box the dark angels army = 535 points (with no upgrades or addons, just bare units) and the chaos space marines army = 460. Thats a almost 20% point advantage for dark angels, but isn't this box supposed to be even when the two armies play eachother? Can anyone explain this to me?

Thanks <3
