We had a(nother) discussion about this recently.
Frankly I don't think the strength of the patrol is the issue with this encounter.
The real issue is that the players are INSISTENLY directed to reach for it as soon as possible, when it could turn out to be a deadly trap for them.
It's especially aggravating because once the event is triggered and Lae'Zel leaves your party to rush ahead and speak with them, there's no backing off without losing her permanently.
