Just because I had seals to burn, I did some testing last week. I went from all my points into MND to all my points into VIT. My Cure went from doing an average of 1100 with full MND, to 1050 with full VIT. And my hp went from 4132, to 4598. I switched back immediately, because I don't need that much hp, but it seems to me the effect of putting all points into mind is grossly overstated. As I pick up more Daystar gear, I'm seriously considering putting all 30 points into PIE to make up for the lack of it on Daystar gear.
