Currently when using ground targeted skills you have to click them, aim them and then click again. This can be problematic as the game sometimes doesn't recognize it fast enough, especially when it's an oGCD like salted earth, when you're also clicking other skills in quick succession causing the skill not to go off.
I'm aware that <t> macros and macros that just spam the skill 15 times exist but <t> macros are bad for when you need to place the skill somewhere to hit multiple targets and the 15 lines spam is not as consistent as well.
GW2 does this already as you can see here and it's extremly useful.
tl;dr: give us a <t> macro where the target is our cursor.
