It’s definitely both servers. It makes a datestamp to keep from popping up more than once a day, per character. It appears on zoning or login, but I haven’t seen it any other time.
Is advertising in the launcher really not enough? We already see that even more often, unless we’re staying logged in more than 24 hours at a stretch. What possible benefit could there be to advertising subscriptions upon login to a server that requires an active subscription in the first place? And without even explaining any details of the pictured benefits?
It does not check whether you’re zoning or logging into a hostile area where there may be something you need to see immediately behind that huge block of nag screen right in the center of your view. It also requires a mouse click on an X button to close it, not just a quick tap of the Escape key.
This is, imho, a significant step backward in “quality of life”. Displaying the same ad to every character every day is inexcusable. Failure to check whether this popup is likely to get the character killed is inexcusable. Not immediately closing with the Escape key is inexcusable.
I haven’t found a means of blocking the popup yet, but now I’m going to have to waste my limited game time on that until/unless FC backs off on this pointless annoyance.
