So my macro on my classic era mage for Remove Lesser Curse is the following:
\cast [@mouseover,help,nodead] Remove Lesser Curse; [harm, nodead] [exists,nodead][@player] Remove Lesser Curse
However, when I go to hover my mouse over a raid frame, it doesn’t remove the curse if they are cursed. I don’t really understand why this is happening. It will, however, cast on myself when I’m not hovering over a raid frame. What’s strange is that it will cast when I hover over the player’s character itself, but it will not cast if I hover over their raid frame.
