This system needs to go. Part of the idea of the Armory system is freedom to play what you want when you want, but implied is the freedom to play a single class as much as you want if you so choose. Any system in an MMO that punishes people for dedicated playing is an inherently bad idea, since an MMO should be designed to get people to play as much as possible. You say it's solved by changing classes, but what if I only enjoy one class. For a year in FF11 basically the only class I played was Paladin because I just didn't enjoy playing as other jobs, and I got by just fine. The game shouldn't force me to play jobs I don't find entertaining just for the hell of it, I should choose to play those jobs when I feel the urge to.
