I'm struggling with this decision as well.
Currently I have 30 Int.
other combinations I have considered:
15 Int
15 Mind
30 Mind (that would more or less signal giving up on the summoner job, which is a possibility if nearly all content is going to require quick-kills on soft adds)
10 Int
10 Mind
10 Vitality
30 Vitality (hey that's 435 health)
Currently, it's 30 Int so that the SMN role (a "Damage Over Time" role) can have a ghost of a chance of handling soft kill-quick-or-die adds. Meanwhile Scholar feels pretty solid with no gaps in ability, so I am hoping it can get by without bonus points at all.
