As the title states it would be an toggle-able option in the general settings that would allow you to cast any ground targeted aoe directly on your target (like in GW1).
Anyone who has ever played an elem,staff necro or the ‘oh god why is my auto-attack a gtaoe grenade engi’ will agree with me.
Please for the love of all the five gods (and Dhum,Abbadon and Menzies) this has to be implemented.
