Have you studied arithmetic SE?
On the very base level, like elementary school?
You have 19 servers for NA (population around 320 mil)
You have 26 servers for Japan (population around 130 mil)
You have 6 servers in EU (population around 740 mil) ... just perfect.
Ok, let's presume that in Japan all 引き篭もり with nothing else to do will go and play FFXIV:RR so you really need servers with low population for them to feel comfortable.
So let's ask you about this ridiculous disproportion for NA and EU. Do you expect anything else but heavy load, unable login, errors etc. if we have 10 time difference in server population?
For me this 2 days of early access were like:
login -> "Please log out asap! <Oh sh...!>" -> login ->error 90000 (1017) -> "Please log out asap!" ......
And no, i will not play at NA or JP servers. I am not really interested in MMO with latency of <200.
PS. Game now feels much more beta than it was at phase 3. Are you really sure that it is ready for release?
