Was planning to reply to your post point by point but then I just didn't see the point of doing it. I've asked you to explain what does the faction has to do with whether Kul'Tirans can get an new model and High Elves can't. You have written paragraphs after paragraphs seemingly answering this question but in fact not touching it at all, essentially dodging the explanation and then claiming that "I don't like your arguments" or "ignoring nuance you provide", lol. Well, sorry, I don't see the point of me saying that your arguments don't work and don't actually prove your point and you saying "I just don't like them" over and over again.
To be fair to you though, you've finally given a relevant argument about this point in your last post:
"Such as the developers stating "The body type of the kul tirans is not exclusive to them and is going to be used for all humans.".
Which means, if you are someone who RP's, that kul tiran body type can be used for someone who is from Stormwind, or a non-infected Gilnean, or a human who lives in a village elsewhere.
It is not exclusive to Kul Tirans."
This argument though, first, is wrong, because when you choose a character, you choose a specific member of a specific faction. For example, if you play Humans, you are not playing an Alterac Human or Gilnean Human, you are playing specifically a Stormwing Human from a specific time and place. And while you can RP by pretending this is not true, it is still pretending that you are playing a character you aren't actually playing.
Secondly, a Kul'Tiran body type being exclusive to Kul'Tirans gameplay-wise but not exclusive to them lore-wise is an argument in my favour, not yours.
Some of your other arguments were basically you telling me what I should like and accept which is just silly and not worth a serious discussion.
Again, the faction identity argument is the only one that matters and the only one Blizzard considers. I seriously don't want to waste time on other irrelevant demagogy. Wasted enough of it.
