Maximizing the utility of masks they already have is quite productive actually, pet peeve of mine for the ME Series was that, even though there were a handful of variations in scalp textures in the game, only 1 of them was actually in the CC (and it really wasn't all that good either), seemed like an absolute waste. To see a lot of different scalp masks in the CC this time around was actually good step in the right direction, it's just a shame they didn't include more unique hair meshes as well. Not only for vanilla pick initially but also the choice of replacing them with custom meshes later.
I can understand they keep unique character meshes out of it though ideally they would have compensated there and made variations for the CC specifically. Maybe next time or in a future patch =)
It's all a bit hit and miss with the CC to that extend, for instance the number of facial complexions I'm completely happy with especially considering we only had three in the ME Series CC.
Then again, they changed and removed tattoo's and could have added a bunch more choice there. Continuity is important, so the fact that we're missing DA2 tattoos in the Hawke CC is ridic imo.
At any rate, more choice is better regardless because it's always easier to replace existing assets rather than introduce new ones, especially in the CC.
