I keep my Mind and Intelligence about equal, so that if I need to cast a BLM enfeeble in an emergency, it sticks. What I do, is boost my Mind to the point where WHM enfeebles stick on IT mobs, and put the remainder to int. After all, +2 int is better than +3 mp in terms of cost effectiveness. The morion earring does both, +4 mp like the best MP earring around, and Int to boot. As for the Wizard's Earring, well, every so often, people ask me to magic burst when no other mages are around. Also, it's handy for farming with ga spells. I try to have good gear, but I don't carry specialty equipment for all facets of my character. Some people carry enfeebling gear, mp gear, resting gear, etc. I only carry one well rounded set.
