I’d love functionality somewhere between basic casting for ground targeted abilities and using [@cursor] macros. Inspiration is MOBA-style quick cast on release. Press button down and hold it down. While held down, the targeting reticle appears. Spell is then cast when you release the key press. Removes extra inputs required to cast the same way [@cursor] does while also retaining the ability to aim more precisely.
Could have interesting interactions with empowered abilities in Dragonflight - assuming they aren’t already being designed so that you can freely aim while charging.
