Not wrong. I never said people didn't leave. I said it doesn't take more than a minute or two to get the party filled back up when it happens on Aether. I keep join in progress on. I'm usually one of those people filling it back up. It is very rare on my DC to get a Castrum run where we stay small without people slotting in. So it's not really affecting the run if people do leave. Those who stay and join in progress types balance out those who instantly bail.
