In a note he added that the feature now is server only. So, they'll be probably be asking about what the community would like added in the future, regarding Group Finder.
I would love it as a feature. I have been leveling many character and when I'll hit the level cap I would not have the time or the patience to find a group myself. A cross-server group finder would do miracles to low population servers (I still believe server transfers/server merges would be a better solution) in additionaly to leveling a new character. Finally, I believe that a Group Finder for operations could be a success if they would only allow Story Mode Operations to use the feature.
What your thoughts guys? I would also add the link to the official site to give feedback.
