There's a problem with Hamlet Defense that I see looming. There isn't enough incentive to take part in the actual fights (which are quite fun btw). The drop rates are randomized and the drop rates seem to be quite low.

In order to get higher supply ratings and get extra chances/points the server as a whole needs to work their butts off to do it, and also spend a decent amount of Gil in some cases. Outside of turning in items for Anima, I don't see players taking part in the supply rating or even the battles because it becomes just another grind with a luck factor. Dark Matter, and Prisms? Really?

My suggestion is that rather than randomized drops to the party. Square should implement a currency that can be scaled based on the score you receive inside of the Hamlet fights. These in turn can be exchanged for items such as the Hamlet Digger Helms. Also perhaps even add in Grand Company Seals or even Gil as another sub reward to give more of an incentives (and for the love of Odin, scale down the damn Anima rewards >.>).

They really did a good job with this content, and I don't want too see it be forgotten about a week after its inception.
