Update: Yesterday and today, can't do anything at all. Just sitting in Mor Dohna with the DC icon by my name. My tracert to Shiva's IP looks like this:

Traccia completata.

Really, I just want to play the game I am paying for.
The fact that I had ZERO connection problems/lag/latency issues when PS4 wasn't supported makes me think the issue has something to do with it.
I still have a lot of time left on my sub, but I just might quit the game altogether if this keeps up, it's been more than a month where I can only play at 2 AM (and not always).
