The truth to be told, I'd rather have the charms again, not the gemstones. Gemstones were in Diablo 2, if there will be in DD, people will call it "rip-off".
The moment I saw charms I likened them to the
Diablo 2 gemstones. But a cosmetic change is good.
The moment I saw gemstones in Diablo 2, I likened them to the materia in Final Fantasy VII (the basis for the magic system, as well as providing stat bonuses and different skills). <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
If my memory was better or I had played more RPGs, I could come up with older examples of being able to customize equipment or get bonuses by using charm-like objects.
