Can't connect with Linux

[dieselboyy]

So, the problem is kinda easy. I followed the tutorial for installing wow freakz on Linux, but when I log in, it gets stuck in the "connecting" screen.
If it helps, when I open Hearthstone (Of course, though blizzard app) I get the big start screen ("HEARTHSTONE"), and then closes. In my opinion is a problem with the connection of the games with the database (Not sure. Hearthstone was just another example)

So... anyone could explain me what should I do? I have dual boot, I play on windows, but I want to migrate to Linux with everything, even games. (AND YES, I KNOW linux is bad at gaming, but my system can do easy 60-70 fps on Linux)
