trap skills or any aoe (rune of haggarad)

can an option be added to trap/aoe skills to be ground casted instead of target cast? some mobs are pretty huge and the runes kept getting cast at their feet instead of the area that i want it to because their huge frames blocked the area that i wanted to place the rune on and changing the camera angle might get my char killed while fighting.

Runes can already be cast anywhere. Your problem is that some hitboxes are too large for what you want to do. Unfortunate but unavoidable.
