Hiho
Sigils are AoE targeted-on-the-ground spells. You have to:
1). Click Sigil's hotkey with keyboard
2). Hover mouse on the ground
3). Press Left Mouse Button to cast Sigil
Is it possible to make such a macro, that step 3 is completely skipped?
So the sigil is used the moment you press the spell, at the place where you currently hover a mouse cursor? (as long as the mouse cursor is in a proper yards range, that is)
Just like smartcasts in League of Legends or HotS and I suppose Dota
