Well...

I'm expecting this to fail spectacularly.

Given that the FFXV event already overloaded their instance servers due to a questline with 2 solo duties in it... It was to the point where when I was trying to do some solo unsync'd content the day it came out, I had to wait upwards of a minute to "Reserve an instance"

Now what's going to happen when everyone's trying to cram into the same zone...
