How many Val'kyr does Sylvanas have left now?

[Ëlësåna-maelstrom]

So... Killing Brynja was the supposed "Vengeance for Teldrassil," right?

“Who’s to say she can’t create more [Val’kyr]? I mean she basically has the Kyrian at her disposal, and Odyn was able to, by sacrificing a single eye, create the power of the Val’kyr.” That lasted, what? Less than a year before they took the supposed revenge back and gave Sylvanas supposed access to an army of Val’kyr to replace the one Val’kyr Tyrande took from her?
