I've had quite many situations where my next spell is going to be Starfire because of spell queueing but SS procs just a moment before the cast, thus interrupting Starfire for SS within ~0,4 seconds (or maybe even less) of the start of the cast quite possible.
Also seeing your SS proc overwrite during the said Starfire is heartbreaking which happens too often, especially when multidotting.
About 5.4: I really hate the SotF change though, I guess it's going to be FoN all day every day if the 4set is not going to change.
