Seems to me that a lot of our spells stack with other jobs who cast similar spells. They do not stack with some spells,

Example, Blind II and Kurayami NI. (SE needs to change this 5/5 merit spell should be better than a lvl 44 scroll spell)

This is why SE needs to make enfeebling and enhancing skill determine the potency of all of our spells, it will automatically vault RDM to the top support MAGE, thus giving us a reason to be invited.
