I upgraded to Fedora 30 and it currently has Wine version 4.8 (Staging).
Guild Wars 2, a popular free-to-play MMORPG, has a trading and gem store interface ("Black Lion Trading Company") that is implemented as a Chromium component embedded in the game, so it probably also uses its own networking routines separate from the rest of the game. In my Wine configuration it just displays an error message
Code: Select all
net::ERR_FAILED
I installed the latest stable Wine version from WineHQ and it works brilliantly. It installs to /opt so it won't interfere with the distribution's own Wine packages. Installing DirectX 9 with Winetricks makes the game run smoother. I'm using 64-bit Wine and 64-bit game client.
(I'm just writing this in case someone facing a similar issue finds it helpful.)
