Sorry if this thread has already happened, I took my time to search the forum but couldn't find anything. However, some new discussion might be dredged up given that people may have had time to adapt.
So, since the release of Black Crusade, what rules have you transplanted to Deathwatch? I know the Swift/Semi/Dodge/Parry whole kaboodle is a common swap as it's more elegant, and that the BC weapons follow in line with the DW 1.2 Errata's optional list, but what other rule changes have you found work in Deathwatch with success? Possibly things that you've now had time to test out?
I'm trying to figure out how to best implement the new Zealous Hate, but it seems DW has some issues with it, such as Marines halving critical damage. Maybe have, since it is just the effect afterall, that this ability doesn't reduce the 1d5 roll on the Critcal charts?
