Marauder Ran Away?

I ran into something I haven't seen before on a Lambda Trial, and was wondering if this is a WAI feature.

I was running with a 7 man team on Lambda (someone never zoned in for some reason) and things were going fine. When we started working on Marauder, it was obvious we were making a good time on it. After his second leap (60% health mark), he leapt to his spot next to the Chamber (NE corner, I think). Now, at this point, all players were INSIDE THE COMPOUND, heading directly to Marauder. As we got close he leapt onto the outer wall, hung out for a couple of seconds and decided he'd had enough.

We got the message that "Marauder had chased us out of Lambda" and got the FAIL reward (which consisted of all of us scratching our heads). So, is this WAI, has anyone else seen this? Or has Marauder finally had his fill of Lambda runs?

Kill 'em all. Let XP sort 'em out.

He's probably upset about not getting any Very Rares yet.. The grind must be getting to him.

its there to stop teams pulling him out of the facility and away from the ambushes that spawn, I believe the jumping around was also added for the same purpose, so he spends even amounts of his health near all the doors, to encourage you to close them all.

Why, if as you say, nobody was on the outside he decided to do that is anybodies guess, maybe his target was a flyer and he decided he had more of a chance of getting him by jumping up there.
