Seems crafting is going to be a decent part of DA:I. Not only the weapons and armor, but obviously crafting potions. With the set ups I usually have, never consisting of healers, potions was always what I depended on, but I always ran out too. I think there is a bigger focus to really use your skills in DA:I and that's not a bad thing at all.
No offense to anyone, but Wynne wasn't the most interesting of the choices available in DA:O. Though I did like her. Anders is liked by some, but I never really found him too appealing as a companion. In DA2, he seemed a bit too dramatic as well. So there went the "healers", unless you chose to play that role yourself. I am imagining that if we did have a healer in DA:I, he/she wouldn't have been my first choice again. Maybe, maybe not. Potions will do me just fine as I choose the group of my liking.
I haven't seen it, but I imagine we still have the ability to use the settings to automatically heal ourselves at certain percentages (yeah, I forgot the name). We'll be fine.
