My question is, I wonder how close it is to Darnassian. It's times like this I wish perhaps warcraft had an expert like Tolkein writing it, he was the language genius. Ofc, accurately, he presents the langauge of the immortal elves unchanged in the millennia of their time. I get a sense he really carefully captures how a very long lived sentient race would be. Details lilke that made them feel so realistic in a way I've been craving for warcraft racial lore to be. But it takes a lot of pain staking time, research, and learning to get right, not just a creative genius flare for telling a good story.
With both education, and high intelligence, there should be no change in language spoken by either the Kalimdor Night elves or the Nightborne, seeing both were the same original elves and originate from Suramar. As a dialect of the original ancient elvish - which I presume is Darnassian????? I don't think there really should exist a variation or if it does, it should be very small.
Subsequent children born, would be taught the language of their parents too, and being educated, with all the language and books, it should remain unchanged. Both Night elves and Nightborne were 100% night elven societies when they went into isolation, and both have the same people still alive. Most of the druids have been asleep for thousands of years anyway, only the females have been around the whole time amongst the night elves, and amongst those who became nightborne, even less has changed, less variation, no devaiation.
Unless Suramar originally spoke a dialect of ancient elvish? Also I thought Darnassian was the original language of the Elves - i.e. the Ancient Elvish, again, I don't see why or how supposedly intelligent beings, with learning and particular to attention would have experienced a language change.
I'll be very disappointed if blizz keep making unrealistic changes to language just because of gameplay. They should never have bothered to try and create an undead language, or make different groups who should be able to understand each other, all of a sudden not understand each other - they should just simply not allow communication between alliance and horde...and then try to make the lore as logical and realistic as possible.
Even Thalassian being largely different from Darnassian is also a stretch, only a handful of generations have passed, and while the High elves were subject to far more outside influence then any of the night elven groups locked way in the 3 main locations were, still they were educated, and highly intelligent too, the language change should be slight. Night elves and nightborne should be able to understand each other with only slight variations in the language, certain idioms and phrases different, different weight on certain words, but also key phrases different , but in the same language. And both should be able to understand Thalassian.
Is this something else gameplay ruined?
