The difference is that Krampus only works properly when she's there at the START of Rage. Rage Gauge- skills don't reduce the bar based on the maximum, but by the current amount. In other words, if you bring four -30% Rage Gauge skills, you can't skip the entire Rage phase. "Only" ~76% of it.

So if Krampus joins the battle midway into the Rage phase, the effect of her skill is halved.

Does that make her worse? I... don't know, honestly. Like -15% is still a lot. But I have my reservations.
