I gave up on it. There’s only so many mount disappointments I can fit in to each week. I’m at around 70 or 80 on Anzu, I’ve been running ZG since it released in Classic and I’ve never seen tiger or raptor, I did about 100 days on polar bear before giving up on that, I did MGT for all of SWP phase, saw bird twice but didn’t get it and I haven’t gone back to try soloing it even though it probably wouldn’t be that hard.
I ended up getting both Thunderfury bindings before getting a single raid/dungeon mount.
