Still an issue, still unacknowledged from what I'm seeing. Every time I use a wayshrine it's like a lottery to see whether my mount runs out of stam in 10-15 seconds (and then the regen is *terrible* after that) or whether it can go for much much longer as it's always done.
It was acknowledged on August 30:

There have been a lot of threads on this subject, but they will generally only reply in one. The Dev Tracker is helpful in seeing where a CM/dev has made a comment. (It does not track moderator comments, so it’s more useful than looking for the Z logo next to a thread.)
As of Gina’s post, they were still investigating the cause of the bug.
Thanks. You'd think instead of general discussion it would be confirmed/acknowledged in the forum dedicated to Bug Reports but ¯\_(ツ)_/¯
