Intelligence is a excellent supportive secondary skill. Especially in large and extra large maps, where heroes grow to be more "mighty and magical", the amount of mana points may become crucial.

Dungeon heroes may be able to pass Intelligence, because they typically have the opportunity to build Mana Vortex in their cities, which basically has the same effect as expert Intelligence – the spell point maximum is doubled.
