After seeing the question answered, I do have some small hope they will eventually come to releasing the hairstyles for viera. Before I address the rest of my thoughts, I want to C&P the translation of what he said from the discord that pushes translations out to discord servers.
"First off, the reason why Viera and Hrothgar can't wear hats right now is the following. We have very standardized specifications when it comes to head gear and the unique design with the long ears on Viera doesn't always meet these specifications. If we allowed every head gear piece, it would lead to clipping or other errors. The unique design of Viera and Hrothgar just prevents us from allowing these pieces, if we want to follow our specifications. Nevertheless, we are aware of player feedback and we are definitely not the kind of dev team that ignores their players feedback. There were a few things we said would be immpossible to do, but we worked hard on it and made it possible in the end. We have regular meetings, I was in one just yesterday and we're planning on having another one this upcoming week, where we discuss how to lower development costs or which options we have to add more hairstyles. The players can be assured that we are aware and are thinking about this, but I am asking for a bit more patience and that you wait a little longer. I hope to have some good news soon."
So to me, this confirms that they are aware we are upset, that this does need addressing. But it looks as though like I said, a large part of the problem is that they don't have the resources to focus on sorting this out. So this is absolutely something that will get worse with releasing male viera and hrothgar. It does irritate me that the people who have been the loudest are the ones who will get what they want, even though they too will end up feeling the same frustrations after 2 years of playing the race they want.
But in the hopes that someone might see this, I want to say, please please just let us choose how much clipping we're ok with in regards to hats. We're fine with ears sticking out when they might not make sense to. We're totally ok with picking our hairstyles to suit a particular hat, back when I played other races, I had to do that anyway. Viera heads are really not shaped so differently. So please, stop blocking hats for it. You don't need to put anymore resources in to makign them fit "right". To back myself up, I'm going to post a picture of the healer headband that just came out in the newest Bozja stuff. https://imgur.com/7Fps7gZ
This hat clips pretty badly with the hairstyle I was using. Had I wanted to wear it, I would have just switched styles. Players make this choice on a regular bases, why can't we? Why do SE find other undesirable visual aspects such as pixelated textures completely fine, but clipping is not? It's completely baffling.
