Make up a queue like Duty Finder, or novice hall solo instances.
So we know we will enter the instance, and when, it will make things smooth and stop the forever clicking on NPCs.
The system already exists in the game, just implement it for this kind of instance, for the time beeing.
They honestly should have known just from the purchases of Stormblood alone that it was going to cause problems if they didn't come up with something.
It looks like amazing content, but I am not going to pay $40-$60 for something I can't use. It's honestly really annoying, frustrating, and my patience is all gone.
I'm taking days off from work unpaid to play this game as early as possible and I can't do everything I'd like to. 60-63 on fate grinds alone is not fun at all.
