It is also worth noting that it might not ALL be doom and gloom though. If you remember, during EW they had really rough servers that they had planned to update, but could not get the hardware for because of pandemic backlogs. Since then, every single region (except OCE) has had an update to the physical servers with the intention of being able to handle more people online at once. Combined with the additions of Dynamis and Shadow to NA and EU, so long as people are willing to try it, I think with perhaps the exception of day one, it might have a good chance of going better over all.
We can't really do much other then just wait and see, and have a backup plan.
