Just wishful thinking to make farming crystal easier. When weather changes to match corresponding elemental types all crystal drops rates increase by factor of X (1-3).
So for example, your farming shards which have 1 at node would be increase by factor of x to be 2-4(plus your normal increase thru luck and skills use).

If your discpline of war/magic, you could go around and farm sprites and elementals and their drops rates of would increase.

Or we can go back to old days and all mobs drops some elemental crystal of some sort.
