I went 30 MND, because of the two jobs I pay Scholar more and it's a multi-purpose stat for SCH because of Cleric Stance. I have more than enough hp and mp for everything I've done so far (coil 1-4 and garuda extreme) so I'm not missing out there. I used to be 30 INT back when I first played the class before I realized I'm better at SCH, and I found that I miss the INT as SMN much less than I missed the MND as SCH. Your dps is definitely higher as SMN with 30 more INT, but it doesn't make or break a fight usually. The extra MND as SCH, however, has made healing less stressful. Especially when you consider Adloquium crits multiply the difference even further.
