Considering transfering here.

[MistakeNot]

But now it will cost to transfer, as of 7/18 since it is no longer a 'preferred' server. Also no more 1m gil and sub 15 day bonuses (100% xp bonus still in effect to 60)

What are you talking about? Louisoix is still considered a new world (never was a preferred world) and still gives the same bonuses for new characters and people transferring in.
When the status of the server changes (which will happen at some pint) all the extra bonuses will disappear - including the XP bonus.
