The better question is; why are you popping Swiftcast and then casting Ruin II.

Seems like a Pebkac issue.
Because Swiftcast doesn't consume other Instant effects for Black Mage, so it's an inconsistent cooldown. Given that it's not traited, all instant spellcasts should be treated the same when interacting with Swiftcast (Which is to say, it shouldn't.)
