There's nothing wrong with getting burnt out for a while. Take a break from FFXI and play some of the other excellent MMORPGs out there for a month... WoW, Guild Wars (doesn't deserve the first M, but still fun), EVE Online, EQ2 (okay, not that one), etc. Sooner or later you'll remember all the fun things about FFXI and come back. Also, seeing all those other games get things right that FFXI gets wrong will increase your bitching & complaining credentials when you do return.
