The problems they're facing are many.
No AFK-logout system, no logon queue system, too few servers to accommodate a growing population, software instability server-side, people playing on servers they don't want to be playing on only because that was the only server available, people asking for free transfers, others.
I can see the extra servers resolving problems for people who are coming to FFXIV, but people who are already leveling up on current servers will not want to start over on a new server, specially after wasting so much time on 1017.
To resolve the problem completely, they have to:
- Implement a functional logon queue system that supports more than the current 300 players
- Implement automatic AFK-logout to reduce unneeded load
- Obviously, increase the amount of servers, at least double what they have now, and have another batch ready to go with the click of a button
- Implement free transfers from existing servers to new servers for a limited time
