If SE were to implement the two stat weights, maybe the NIN will have different stances, similar to what clerics does. There are already items out there that give both STR and DEX, some with VIT as well. It is not too far fetched that SE would take us in a different direction with both stats. Being in "x" stance converts all dex to str for X skills, being in "y" stance converts all str to dex for y skills. Kind of like clerics I spose.

Who knows. Maybe we will in a month. As for now though, I am saving all this MNK gear that I am getting for just in case.
