Mild agro systems make sense. If someone's trying to hit you with a sword it's hard to pay attention to anyone else. The best way to do it would simply be to give, oddly, tanks major bonuses if their target attacks someone else. "Ok, you're not paying attention to me, so I'm going to cut you up" then have the AI take that into account (and have enemy tanks do the same thing to your party members.)
As for spirit healers. Probably mostly necessary on the hardest difficulty levels, probably not necessary on easy/medium. However, I suspect you will be able to create specialized groups which can mostly do without them - for example, 3 rogues/warriors two of whom are archer speceed, one mage with glyphs - scout with stealth, once you see the enemy, drop a pile of traps and glyphs, have the archers activate the encounter, fire while backing up, let the enemies slaughter themselves on traps/glyphs. Doubtless other emergent strategies will be possible, especially with multiple mages.
