I'm having some trouble with getting a group too - i'm on my third day of trying - currently sitting at 48 mins waiting. I can confirm that the language tip that was kindly offered doesn't work (for me at least) all of the other language selection options are greyed out.

I just want to say that I really love this game and so far the story surrounding the Crystal Tower has been really compelling. I also totally get that the story in this quest line has strong relevance for Shadowbringers and that the devs want us to experience it as a result.

But if this is mandatory specifically because there is story relevance - then surely a better option would be to either completely nerf it so it can be experienced solo in some way, or just create a small vignette or cut-scene to fill things in? It just feels like we're partially going through the raid mechanic motions for the sake of it.
