I always wanted to see crosshair spells in World of Warcraft. Imagine having to dodge stuff, target stuff etc. It would expand the skill cap so much.
It could be just a few spells or so, say you click a spell and a crosshair appears. Like a buff that you can cancel.
It would be cool in Classic + too
I would prefer if it wasnt a static one like cs:go but a small dot that follows the environment like in heretic 2.
