Hybrids in this game are generally a physical damage dealer picking buff and utility skills which don't require points into INT and using them to complement and aid them.
Pretty much this.
Every hero should dabble in the main schools of magic, they're just so helpful for the buffs. However, you can't really afford to 'do both'.
It's funny, there's a Battle-mage class in-game, but it's not viable at all, which is disappointing. The closest 'battlemage' thing I can think of, is my Sebille rogue with poisoned blades.
