1. All of the Divinity games have been using a classless system, so you should be able to turn your character into as much of a battle-mage as you wish.
2. Only combat will be turn-based. Within the real-time exploration it should generally be possible to fully heal your character between battles. Unless you run out of healing stuff, maybe.
3. In turn-based combat, there's no need to quickly press a key, but I'd still like to have a quick-key bar. This way, you can assign keys to the skills, spells, or items you use most often and only need to open a full menu for accessing the rarely used ones. In my eyes, that's more convenient than clicking, plus it allows you to quickly use something in preparation before entering combat.
