I just posted about the targeting issue. Highly agree with you!
I also strongly agree about the AI positioning. I will painstakingly get my group just how I want them and then as soon as combat begins, they scatter into horrible, move-wasting, positions behind skill blocking terain, or out of range.
I also like the auto-collect suggestion, but that could take some work. We would need to be able to specify what to auto-collect. I.E. potions, scrolls, ammo, gold, etc. Some people won't want plates or even some items you and I consider valuable. At a base, they game should assume to autopickup all gold ;) But even then, they can't move our characters to the items, so it would have to be in range of normal pickup only.
I would like to be able to view multiple quick bars at once. I am not a fan of scrolling quick bars often. stacking 2+ hotbars would be handy IMHO.
