I assume he meant the support beams, but not really that funny.

I agree that DoL should get exclusive items, but soon that will be the case with the materia catalyst, assuming there will be more than one kind.
I am not sure about the treasure chest idea as its not much of a hiding place in most trees. it would of course work for fishing but hiding a chest inside a rock face would be mighty tricky XD. But I do want rare/ex gear im just not sure if this is the best way.
I would like to see an instanced area, like the area outside the botanist guild for trees and such, a sort of sancuary, or mines you need to be rank 50 before being able to go in for example, would be quite nice.
