You have a system that encourages playing every job but you are only allowed to gear one character unless you wanna spend millions of gil on crafted gear. What if someone doesn't want to craft? Yoshi's view on the game is someone shouldn't have to do certain content to get certain gear yet if you DON'T have penta melded crafting gear you are griefing.

You make an expansion that promotes playing continually then turn your savage content into a once per week event and do not allow people to go back and play them again without griefing other people's rewards. This system is fundamentally counter to the nature of this game, it needs improved because it's not fun it doesn't make any logical sense.
