Maplestory "High Five" Private Showcase

Then why have it at all?

It makes no sense that you level up 5 Cygnus Knights to 120 just to shave one second off a 30-second status (and even that is only if they round up).

Maybe it's the next useless stat, maybe they'll scale the current values up a bit. It's also possible that we also just don't know how status resistance works now, maybe the reduction isn't a percentage based on how much status resistance you have out of 999.
