But it's proves nothing - until you have some numbers to compare, it's inconclusive.
Imagine they made the Drakthyr buffed up from the starts. What would happen then? Many of those who like the buffed up option wouldn't be here (by the simple rule that people who are happy about something are always less vocal than people who are unhappy); we'd have a thread calling for slender Drakthyrs and we'd have fan art creations with thousands of likes for more slender Drakthyrs.
You repeat the same mistake again and again: you see some people sharing your ideas and you attribute them to the whole "community", arguing that it's something "people expected from the race". Yes, there's a group of people who want buffed up Drakthyrs, but raw numbers prove that more people play slender characters. You can justify it however you want, but it's a fact - and your justifications (lore, fantasy canon etc. etc.) are speculations. You can't know for sure WHY elves are the most popular race. You can theorize about it, but the only known fact is that more people play slender characters.
