Blood Elf story is over? Is that a fact from the top devs or is it your personal bias against the Sin'dorei because they are Horde? And the Windrunner family are now all exiled from Quel'Thalas. The remaining ones anyway.
Theron and the Farstriders remember Sylvanas for the hero she was, not the villain she has become.
Is Horde story over because it's the Horde?
Void Elf story is over - Blizzard told me in 8.3.
Your just obsessed over Quel'Thalas and still angry that it's Horde land. Quel'Thalas belongs to the Sin'dorei.
The Sin'dorei are Quel'Thalas and Quel'Thalas is the Sin'dorei.
You need to get over it - you'll get some pretty Night Elf stuff if Blizzard do a revamp. Make use of that, whilst the Horde will make use of Quel'Thalas.
