Shandris stopped being mean to the Horde player within moments of seeing them in Shadowlands. Then she worked with them in Zereth Mortis without any hostility. And continued to do so in Dragonflight when the Horde player joins her to spy on Fyrakk and discover he’s working with the Druids of the Flames.
Then Tyrande works with the Horde player without any problems.
Maiev hasn’t worked with the Horde player in the last three expansions.
