Well there you have it - thank you. And...its readily apparent, since the damage models are different between WWI and II arenas, that they're working on a new damage model for potential implementation into the WW2 arena at some point, and that the knowledge they glean from the WWI arena, if not the actual model itself will be, in some permutation, will be used in the WW2 MAs.
Don't read into it any more than that and the question has been answered.
