I'd love to use Quick Cast for Spells/Skills which are Point target(it says "Target: Area" in Eldevin), mostly are AOE abilities. Sometimes it's tiring to keep clicking to cast those Point target abilities
Adding Quick Cast Option is great, and maybe add an advanced option for Quick Cast which you'd specify which abilities are enabled for it.
Either Quick Cast would automatically cast the spell at the location of the Cursor or
it would cast nearby mobs but actually, it's just auto-cast at the cursor location.
Also, Self-Cast could be great too -Double tap/press the ability to cast it to yourself especially healing yourself.
