Is anyone else having issues with 1 or 2 alts not being able to phase dive?
I’ve tried the following -
One character is fine, but the others I can’t get to phase.
I did read someone else having an issue with it but I don’t know what the solution is. I would wager that there is something in the quest line they need to complete or that they are phased. That is normally the common culprit. I just don’t know what.
Make sure you go in and upgrade the cloak. Just the basic cloak gives you the spec proc, rank 1 is what gives you the ability to phase dive. Talk to the NPC that gave you the cloak and ask him about upgrading it.
On which character, Willowwater?
I checked your Shaman, Warlock, and Evoker and had no issues entering Phase Diving.
Also, you can only enter Phase Diving at certain locations on the map (unless you have a rare drop that allows it anywhere; this is how you get some of the transmog treasures).
So if you are having trouble interacting with the platforms that enter you into phase diving, it is likely a UI issue.
Sorry about jumping in but one of mine is also locked out of phase diving / Untethered Space but he is the one I completed Chapter 3 with, not an alt. I can get into Untethered Space with alts but not with Ogros on Sisters of Elune. I have disabled addons, logged out, shut down client, but no joy. He makes the animations but doesn’t go anywhere.
Help…
Have you completed the full campaign (what’s released anyway) on at least one character? I know that all of my alts that got the cloak the first week had no issues. The final 2 that I tried during week 2 couldn’t phase dive until I completed the campaign on my main.
You’ve made sure you’ve manually upgraded your cloak?
I’ve heard from some people that dying helps. There might be a hidden debuff somewhere. Might try doing the old mount up and fall trick and see if that helps.
I completed through the start of Chapter 4 on Ogros, haven’t done it on the others that have functional cloaks. Will give it a shot.
Status update:
So Chapter 4 progress stopped at Raid. No change.
Deleted Cloak and reacquired. No Change.
Took breakables off and dropped from the sky. Issue fixed. At least for now.
Note do not kill yourself next to the cloak vendor as there is no graveyard on that island and you can’t fly while dead.
That’s so broken.
Hi Vrakthris, would you please check my character Fritte-Proudmoore (US)? All of my other characters can phase dive, but when Fritte clicks any portal, nothing happens. It has been like this since the start of the patch, and there does not appear to be a way to submit a ticket anymore.
Just to answer this part. The ability to submit a ticket usually depends on if it is an issue that Support is able to help with. Outside of basic troubleshooting, such as making sure that you have completed the requirement to unlock the skip for alts, reset your UI, etc… this would usually be something to report on the Bug Report forum.
It looks like you are on your Mage right now. As long as you stay off your Hunter for a bit, I’ll take a look.
I think I figured it out.
I believe not being able to successfully phase dive is happening because you had a rain buff on your character. As soon as I clicked it off the character was able to switch into Phase Diving.
I don’t know if it is intended or not, but you should be able to phase dive now if you want to give it a try. 
Hasn’t this been implicated in a few different “can’t do something I should be able to do” bugs?
Really weird.
What can I say… sometimes the weather really puts a damper on activities. 
I know it caused an issue when trying to get into the storm on Sirens Isle.
Guess that’s why dying tends to work. Good thing people don’t necessarily need to die anymore, just check for a weather buff.
Wow, that is seriously weird, but it fixed it! Thank you so much for quick response!!
BTW I did submit a bug report weeks ago, just came back here to forums (for second time) because the content has been unplayable for weeks. I tried to submit a personal ticket, but the options under Help just lead you around in circles and there is literally no way that I could find where I finally got to entering a ticket.
At any rate very much appreciate that I finally found someone who could help me!
Just to touch on this; the bug report forums is pretty much an on-way street. The folks who handle there don’t reply to threads unless they need more infomation.
That’d be because the ticket system only allows a ticket to be place for something a GM can help with. They can’t fix every issue, nor would they know of every workaround for any given issue.
Please don’t act like this is normal. I’ve been playing since 2007. It used to be if you had a game-breaking problem you could submit a ticket and it would get routed to someone who could help. I haven’t needed to submit a ticket in a while so I’m not sure when things changed, but the interface for asking for help has been changed so you just get routed in circles and can never actually put in a help request. This is actually terrible customer service on Blizzard’s part. I feel lucky that I found a customer service rep in the forums who was actually responsive, because no one ever answered my first post about it, or any of the other people in that thread.
