Particularly when you're standing on top of a keep between battlements. You drop an AOE ability that you made sure lined up on the ground, and they land right next to you, 40 feet higher than where you placed them and utterly useless. What's the point of the "preview" that shows they'll land on the ground when they don't land on the ground?
Why hasn't Zenimax fixed this? It's been forever and there's no possible strategic justification for it. Plus it makes you feel really stupid.
I'm imagining responses advising on how to do it "correctly" so as to make sure you don't hit a battlement, and getting infuriated since it's not the point. Fix it.
