Subjective statement is subjective. Context is important. "Performed just fine" in what? Ifrit HM? Savage Turn 9? Hunts?

You can work without it (we have a healer in our alt coil group who has T9 clears without it, but he's also cleared many times on his main that DOES have Swiftcast) but it eliminates one of many safety barriers for no better reason than "I can't be bothered to level a 2nd job".
