From what I understand, they're not quickslots. It's not a quickbar / hotbar, but simply the "available abilties bar", very much like the "memorized spells" list of NWN.
I can't say that Good Old Slots had not crossed my mind. I know how it worked, and I guess we're lucky not to have any per-level-per-rest restrictions.
Yeah, there were times when wizzards had to plan their spellbook daily, while sourcerers had to count carefully. I could live with that. But that's definitely not the best part to borrow from the old systems.
Hopefully we're going to have an answer.
But why would you have to change your tactics? You have it set up so that it uses both the fire and the ice attack on the enemy,
That really depends on how many tactic slots do we have per character. Like I've got one of my mages specialized both in elemental damage and in some sort of support\cc. At best it means that I need to change tactic preset along with the spell bar. That's if we're allowed to save multiple custom tactics presets.
