I'm with Anarchy Marine if NGS is ship dependent.
If things wind up like base PSO2 global launch, then expect hell to break loose on here, Twitter, and Reddit.
if it ISN'T ship dependent, then i absolutely expect shit to hit the fan. Why? Easy:
if all the ships are unified like the pvp/challenge quest ships for NGS, then expect heavy traffic
and remember this is the global server. i'm guessing a million+ players trying to get in via xbox/PC, steam, and EGS. I'm expecting any of the three to shit the bucket. (and by extension, i wish the arks-layer team a giant good luck due to the above.)
