Whatever blizz did last patch broke some arenas and you can exit the starting area of Solo shuffles as a stealthy and get across the map.
Some maps have fail safes that port you back, but Tol’viron Arena for example does not have one and I can cross the map and wait for the enemy to drop.
I’m not doing this anymore but tested and confirmed it works on multiple maps with rogue just by rubbing up against the barrier in a specific way…
Yep! Confirmed bug. Do not do it, but do report it in game! 
Wo wo wo why are you telling the secrets??
We couldn’t find a way out even with a dh
But why is the rum gate gone?
There was an AV and WG recently where I moved forward close to start and went past gate and was ported back, quite a ways in AV, all the way back into the cave…
Maybe related gate bug?
Sounds like someone deleted the walls by accident.
i saw that in WG, go too far and you get teleported back, IOC was letting you out the gate 5 seconds early as well.
Yah that’s what I saw. I sit back now. Fairly recent bug I think as I don’t remember it happening before I wanna say a day or three ago.
Palpatine told me to!!
I was able to break out of the rooms a few times today. Legit just auto running into them maybe a random jump or two because I’m a spaz.
100% not trying and it’s happening so idk what gives. I think it’s character model related but I could be wrong.
100% happening to Dark Iron Dwarf without effort.
