Doesn't matter. 1% is 1%. Unless high elves originally numbered in the billions or so, it's
damn unlikely they could remain a viable race unto themselves when 99% of them no longer exist.
You're just throwing out the "RPG books are non-canon" blanket without realizing they only said that as a generalized statement since they didn't have the time, in the context of that Blizzcon Q&A session, to detail out exactly what was and was not canon.
Stuff like Booty Bay having a red-light district would obviously be non-canon, as nothing in the RTS or MMO has reflected that info. Primarly, the "this is non-canonical stuff" line is in reference to various locations and events in the books, not the more concrete matters.
Stuff like age/height/weight charts and lifespan measuring would be canon, as those have been reflected in the games' lore (plus, math is math, you can't de-canon things like "Gnomes average slightly over three feet tall", since real numbers are involved). Plus, the RPG books refer to stuff that obviously IS canon, so not
everything in them can be dismissed entirely - or are you claiming that all the various races cannot speak since the RPG book refers to all of them knowing various languages?
