I started playing a demon hunter and my Imprison mouseover doesnt work on my focus using mouseover even if i place mouse on the character ingame. Glaive Toss also doesn’t work.
Never used the ingame function but by reading the tooltip it seems you have to go over the unit frame with the mouse, not over the character.
Just use mouseover macro and you can do both for sure.
Which button are you using to execute the spell?
