I got sometimes bad luck like.
When joined finder in Halls of Valor. If tank or players dont check Fenryr’s paw-tracks on ground.
They go wrong way. I tried talk them and ping mark. But they ignored me and keep thier way. I fought Fenray alone. Rare wiped. Players think Fenyry “always “ be on left or right way. It’s damn RANDOM left or right. They need know or read and see ping.
that’s because when HoV was added to the M+ pool in dragonflight they gave Fenryr a fixed spawn on the right side near the humanoids NPCs
i’ll be honest when i first started playing remix, i went right on my first HoV
but it took me just that 1 HoV to realize that it’s back as random (as pre DF)
so good chance either these player are on their very first HoV
(or second, in case Fenryr spawned on the right the first time)
I have seen Fenryr spawn to the left once for the entirety of Remix. It might be random, but chances are he’s going to spawn to the right, so why bother!?
For me it’s been like 50/50 where Fenryr spawns, easy to see though, I think the people that run the wrong way are probably new to Legion, not knowing he has 2 spawnplaces.
It has been mostly to the right for me.
you know you can see where he is by following the paw prints on the ground right?
I am aware, but that doesn’t change the fact that out of however many times I have been in Halls of Valor, Fenryr has consistently spawned to the right. Except for one single run where he spawned to the left. So the point stands: Why bother looking when he “always spawns to the same side”.
rng probably. For me it’s been 50/50 which sides he goes to
The last four runs he was to the left. 
Just did a 58 (thank god, now I don’t have to do any more of that) and he was, once more, to the right 
This, just look at the Paw prints and you know the side. Its not like they are small..
