I had a couple ideas to deal with server congestion and overcrowded servers

1:
Give us the option to temporarily log into less congested servers
You'd have to block the ability to use retainers on the new servers though using the market board should be alloud.

This will be an easy relief for casual gamers that only plan to log in for short periods to do quest/duty finder content. Though they won't be able to log into chat with their linkshell/free company mates, they can do content to further themselves or craft.

2:
Open the mog station and allow players from over congested servers a temporary free ticket to move to a less populated server (possibly giving them another to move back once all this is figured out)

3:
instance larger scaled FATE battles moving them to another server.
sort of like you see the FATE enemy/enemies, once you attack them you get moved to another server where the actual fate is taking place.

I was thinking this so you could put a restriction on the amount of people participating in the fate (if this is a cause of concern for server congestion) if you attack and too many people are in the FATE you get placed in a queue, when someone HP's because they're KO'd in the FATE the next person in the queue is aloud in.

These are just things I was thinking off the top of my head, thought I'd share and didn't know where, so I picked bugs, since it's a type of bug i suppose.

I'm from Hyperion, so I think this server is probably one of the more overcrowded since we seem to have merged with other worlds that got sent to the jp data centers.
