I honestly don't get what's your problem, all you can say is `linux is unsupported, go away` - nothing clever, nor new, comes from you, nothing that would help anyone, except your ego.

All you did thus far was going into a topic, that doesn't even concern you in any way mind you, and cry like little babies that linux users are hackers are should not get any support from SE.

We don't demand SE to fix it, however it would be nice if they did, all that was left in this topic was the matter `how to workaround this issue` - but nay, not until you, great heroes still have something to say!

You literally did no good, only wasted energy on crying one line, that everyone here was already aware of, all over again... P A T H E T I C

Having that said, the fix is here.
1. Get the latest version of Q XIVLauncher
2. Install windows Steam in the same wineprefix as the launcher/game
3. Login into Steam, enjoy the game.
