There was a famous sci-fi/fantasy author (i want to say Heinlein, might have been Aasimov, too busy to look right now) who had a simple maxim:
if you're using words people already know, stick to what they know; conversely, dont make up new words for things unless you really have to.
In his example, he uses the rabbit - if you're going to have a rabbit-like-creature exist on the planet - just call it a rabbit. Or a near-rabbit. Whatever - but use the term rabbit in there somewhere.... that tells the reader everything they need to know without you having to create a new word and explain in detail how it is like a rabbit but not - etc. You use the term "alien rabbit" and boom, point gotten across, done.
In another example, he does discuss things like "King" - if you're going to use that word, you're using that word with all the baggage and expectations that come with it. So if you call a guy a King - he's got to be a king. If he's not -really- the King but sorta this .. king-like, sorta, really cool specific thing for your awesome setting - make up a new name. Dont prime the reader with the expectation of "King" and then have it be something completely different.
Varian never should have been High King unless he was actually going to be High King. By using that title, they implanted the notion of "King of Kings" in everyone's head automatically.
Should have just called him Supreme Commander, or made up another title that fits better.
That being said, as a million others have said - Anduin is just King of Stormwind. He has not inherited "High King/Supreme Commander" from his father.
Now... he MIGHT have some legitimate claim on "High King" of the humans - as all of the other human nations that still technically exist (Arathor, Alterac, Lordaeron) with the exception of.. possibly Kul'Tiras (since we have no idea what the hell is going on there despite them being within easy travelling distance of all of the Eastern Kingdoms) and Gilneas (still technically a "human" kingdom, even if they have had a race change very recently) are kingless and in many cases outright leaderless.
The case could be made that Varian/Anduin have taken those lands in trust and added them to Stormwind's empire - as vassal states potentially - and the case could be made for being "High King" of the humans... as he IS the defacto ruler of all those human settlements that are not part of Stormwind proper but still Alliance territory (like the settlements in the Arathi Highlands, Wetlands, etc).
