Yes and no. Obviously Tyrande killing Sylvanas would be one of the most satisfying moments in wow, it won’t really do anything. It won’t bring back Teldrassil or the thousand innocents that were killed and burned. And I don’t care about Sylvanas anymore. Her story ended in Wrath and there was no reason to bring her back. Obviously old Blizzard had different plans for her, but they aren’t around anymore so in my opinion they should have had her gone out with a bang. I’m only interested in what our Queen Azshara will do in the future.
