Cannot access worlds!

Although everyone is probably aware of the infuriating problems of not being able to login to the world where your character is based, this problem is most likely being compounded on a daily basis.
Not just by new players creating new characters and logging in, but I expect that large numbers of players are creating extra characters on other worlds so that if one is not accessible, perhaps one of the others is.
This won't be being done by malice or greed, purely as a reason to get the FF fix that we all want and need.
One other problem that this may create is further down the line when users need to start to pay for not only the weekly/monthly time, but also for the cost of each character that they have.
To help with this, we urgently need available worlds and the need for free transfers of characters out of the ones currently full.
I currently only have one character, created on a world that wasn't full, but now I cannot access. This is someone who was part of the beta and didn't get any of these issues at the time. I have now been able to play the game for about 4 hours out of the number of days that I have had the game.

I am not wingeing, don't get me wrong, I realise that there will be issues with a new MMO, balancing the need for space and availability over cost etc, but think that this is not being addressed quickly enough. Surely the utmost priorities for the game at the moment would be for getting people the access they need in order to build their characters and get some involvement and ownership of the game. If this doesn't happen, the long term ownership could be in jeopardy.

Thanks
