I don't think it's working at all. I was in queue for 90 minutes last night after patch and there were tanks in Stormhaven chat saying they were in for 2 hours. There's no way that of all the post-50 characters playing only three of them were in queue so a fourth could never be found, even if there were two new dungeons added.
It does seem worse post 2/8 release. I was at least able to find a group before albeit intermittently - Sometimes after a few mins, sometimes up to an hour or so.
I played all day yesterday and wasn't able to get group finder to work once. I quit between play sessions and queued straight away, and it was for at least 2-3 hours each time yet nothing.
@ZOS_GinaBruno - Is this issue being looked into? It's really frustrating that it's so difficult to group!
On EU server it's still an issue to queue as DD, takes more than hour and estimated time is also more than that.
