Which none of us stated what he said was fact.
No. No, they have not.On the other hand, the WoW game director stated facts on the issue. Facts that you seem to deem as "opinion" simply because they go against your agenda.
Any statement regarding "adding high elves would blur factions lines/identities" is nothing but opinions, not facts. And Blizzard's opinion (doubly so for Ghostcrawler's) in this matter is verifiably false. Faction lines have been blurred already, because silhouettes previously exclusive to the factions have been given to the other.
