I've been thinking about it.
If a spell is an instant spell, it shoud be consuming swiftcast effect?

Firestarter trait says "no cast time" and swiftcast effect is not consumed when a fire 3 with proc ative is cast.

Swiftcast says "next spell is cast immediatly", but for instant spells wich are cast with no cast time swiftcast is consumed.

For me its not clear the difference between "instant", "immediatly" and "no cast time".

For me the behavior for those would be the same.

Is it an issue?
