At the EU main page for the WoW forums, the Evoker class is not listed under “Classes”, if I am not logged in. It shows up correctly when I am logged in. Firefox on Linux. This issue does not occur for the US site.
I would provide links and an imgur screenshot, but every time I try to do so, this forum system for some ridiculous reason tells me that URLs aren’t allowed in posts, which… good luck reporting an issue with a website if you can’t include the URL of the page the error occurs at.
If you want to see a screenshot, go to imgur dot com slash a slash YXZbDC2
