I've had zero issues getting into anything on goblin ._.
Sure, my DPS queue's are longer, but that's to be expected. But usually 20-25 min, sometimes a bit longer.
I main tank though, and that's always fast queue times, so maybe that's why I'm never running into many issues. If it's DF, I dunno why it's so bad for you. If it's specific dungeons/trials, then yea. Some of them are pretty much dead as no one is queuing for them anywhere.
Yes, PF is dead in goblin. Because people simply don't use it. I see groups running around all the time. Most people already have their groups they run around with. You don't HAVE to have 8 people to run around and do some fate grinding. In fact, half the time, I run around and do that solo anyways. Because we're a lower population, many have already found their group/niche that they stick with to get things done. If your FC is no longer active, I would suggest finding a new one. I see plenty of green leafs running around in goblin though. Heck, I saw at least 5 yesterday while I was fate grinding in Coertha's (and that's usually not where you see green leafs). Granted, I would probably say they were most likely alt's and not actual new accounts.
PvP though, yes. I've queue'd up for that for 45 min even with a pre-made party of 4 (meaning we were only waiting for the other team...). But that's simply due to lack of people playing PvP in the first place. Not really the server...
Join a linkshell or a more active FC would be my suggestion.
