A GM has kindly replied to my post on the support forums with the following info.
Well, both actually. Our developers have been tweaking pet pathing in recent weeks to try to improve it in certain terrain. So, its current state is indeed intended, but our developers know that it is not in a great place right now and have re-entered it as a bug and will continue to work on it until they are happy with the way the mechanic functions.Posted by Acherontia I'm both reporting this as a bug and also asking if the devs are, as far as blues know, aware of it; also, was this an intended change?
* * * * *I made a post here (forums are EU, to you US players, you sadly can't post but feel free to repost if nobody's brought it up on US) about the buggy pet pathing since last patch.
I found out we're not alone--DKs have major issues with their ghouls now, too. Someone's mentioning it happening on their warlock, as well.
Basically--ignoring the stupid stances for the moment, and the fact that stances override manual commands, and just going to the pathing issues--pets' pathing AI is broken. They don't won't go up or down zeppelin or AV towers, for example, to chase a target, or up to the ledge in WSG, or even around corners in some cases. Has anyone else had these issues?

Some comments picked from both threads:
Also in the Dalaran Sewers Arena, an enemy jumped off the ledge, and my pet refused to run back, down the stairs, and to them. Instead he simply stared at them. Pretty bad since I'm a BM hunter in PvP.
my pet got stack in dalaran sewers like 3-4 times in 4 days of arenas.
pet always stucks on BE bridge, usually using /petpassive unstucks it
Seen a few fights recently where my pet was stood still on solid ground along with the boss and it wouldn't move, assumed there was a large hit box and that it was still attacking but it was just stuck and unable to attack the entire fight.
This happened to me on nefarion fight-as thought the same but saw that it didn't put the ravager buff on the bosses- it just stood next to me the whole fight- tried everything to make it attack but it wouldn't.
where is my pet? He's standing on the bridge, not moving at all
