So so happy they finally released a statement of some sort. It's nice to know that our feedback has been received as is being looked into - many thanks to the community management/forum moderation team for their part in this communication chain.
Hopefully, the removal of the lip gap was a product of the "mouth scaling" they mentioned and not an intentional design choice and will be addressed. Same with the keeper fangs. I am /pray -ing that the art and dev team understand the unique charm the face 4 features have in their current live state of the game and make the necessary adjustments in the benchmark (or at the very least, provide a clearer understanding of will be addressed during the time between the benchmark re-release and the dawntrail launch). I don't know if anyone in the JP mega thread has brought up the lip gap, hopefully the feedback from this thread has proven that is an aspect that is loved in our characters. In the case that images prove to be a more useful communication tool to pass around, I've updated my previous mouth comparison diagram with a focus on the lip gap:
I only have good photos for mouth 2 so I encourage others to highlight the gap aspect in their chosen mouths
It's tough to say whether or not they can add more toggles to our characters. Keep in mind, every option you have for your character is a data point which requires server space to be stored and loaded. Considering it seems the dev team is in a never ending struggle for memory (think of how difficult it is for them to add extra slots to literally any storage system in this game) I personally wouldn't keep my hopes up. Not trying to rain on any parades here though! It would be nice if there were more options to be had, if there was more room to control the finer details of our characters. If they could find a way to treat add 4 more mouth shapes to make versions with and without the lip gap and 6 more eye shapes to have versions with and without the heavy lashes without it costing too much memory that would be the perfect choice for everyone. I do respect everyone who likes the new mouths and lashes, but I personally hope things are changed to better align with how our face 4 features look in the game right now. This will be my first time experiencing an expansion on launch and as excited as I am for it, I just know I'll be thinking about how they put my girl through a make up filter the whole time lol
