Sorry that I got to this thread late... you may want to consider this, as well: FIRSTLY, Do you currently play on the psn/Internet as accessed through a router or otherwise firewall ?!?!? (This is important)
(If you aren't on a router or otherwise, you can go ahead and ignore this post)
I can tell you through my own experience that this game is very sensitive when it comes to stable match-making.
Up until the recent patch, I was getting a 13 Frame Delay when playing over a router (5-7 now, which some have told me is normal.. but still not good enough)
Worst part was, I hadn't even realized it the entire first hour into playing.. until I attempted an IK, then it happened THREE SECONDS later, as I was attempting a double dash forward (because they moved)
Quick resolves for this phenomenon:
1. Use a direct connect to the Internet, not through your router
or alternatively, 2. Open the ports on your router to the playstation network
(Information on the port numbers for PSN can be found here)

Furthermore, if you have issues with opening ports on your router or have simply never done it before, this site includes step-by-step instructions on how to do so: http://portforward.com/english/applications/port_forwarding/Guilty_Gear_Xrd_-SIGN-_-_PlayStation_4/

Just consider it advice from a friend...
I had to play on a router the entire first day I had the game while a sibling of mine streamed youtube.
I understand the pain of 1 and 50. v_V
