Oh, this is rich coming from a a community which got so many things from Blizzard (first High Elves in WoW at all as Blood Elves, then their model on Alliance side, then non-void customizations) and still asks for more.
Do You understand that by the simple fact of introducing a playable race that’s explicitly called “High Elves” You are already taking from Blood Elves?
You put their currently unquestionable right to all pre-third war High Eleven legacy into question, by creating a playable race that by it’s very name is implied to have stronger right to it.
