I can't see your problem.
You'r addicted to a certain aspect of the game and QQ over it cause the droprate of the item you're longing for is verry low.
Hmm... old Dynamis had the same problem. You had to spend a huge ammount of gil for a chance to obtain what you want.
And nobody cared about it.

Now we have different events where we could get good items and places where we could farm the necessary items to do these events. So in case you'r too lazy to farm, that's not a problem the DEVs have to solve.
If you want to spend gil, it's your decission but don't blame the DEVs!

btw. the prices for Voiddust are droping right now.

PS: #2 Tsukino_Kaji said it verry clear. (^.^)b
