Ehhh, I wouldn't jump the gun on the Q_Q ing.
Like, I've always said that I think they would get "Hrothgar versions" of current unlock hairstyles because looking at their hair it's clear as day that it's not the same as normal hair. It's thick, simple, has no highlights and LOOKS like what a big beastly man would do. So IMO they were never gonna get 1:1 versions of other styles. That being said Im not happy with hearing they wont have "Hrothgar versions" of unlock hair at all ... but I do feel that new completely unique hair styles and new faces to come post release could make up for it provided they handle things well.
Like maybe we can change faces when we go to the Hair Guy to make up for this strange connection (Or at least the 2 options we have for hair for our face). Maybe because of the simple and bold look of Hrothgar's manes they can make them without much problem (Don't have to worry about highlights or making them fancy or detailed. They mainly look like big sections of hair pulled back into a wild style). Maybe these new hairs come with new heads or maybe all the faces get unique hair styles added to them or maybe they share all the new styles. Who knows.
As for twins, as a Femroe I can tell you every femroe I see has 1 of 2 faces. This is true for a decent amount of races actually (Like male Elezen ... big yikes at the lil boy and grandpa faces no one uses). But being a Femroe has shown me something ... and it's that---
1- When a character doesn't look like a normal person it pushes you to play with colors. There are no huge cat men in rl so you can do w/e you want with colors and patterns.
2- Glam, Hair color and skin color go a long way towards making you look different when you're around others who are also rocking the FOTM hair and have your face.
3- You don't play a big huge race to blend in with the crowd. I expect to see many unique Hrothgar out there given how many crazy cool ones I see on the Twitter contest.
