Marchand mission problem

[CreepyShutIn]

According to the wiki, on missions where you bring your teammates, they're supposed to rest and return to the fight a while after defeat. This hasn't been happening for me, and it's really hindering me. I'm playing a Scrapper (Staff/Dark) and Silver Mantis is kicking my ass every time I approach. I've gotten desperate enough to buy the temporary boosts from the P2W vendor, I'm stacking the shield pet with inspirations and every defensive I've got, and she still mops the floor with me. Definitely tuned for a fight with lots more help, so I'm hoping this is something that can be easily fixed. 

 

EDIT: With a lot of luck, I finally made it past Silver Mantis, but now I'm having a similar problem with the Council War Walker, so the allies not resting and returning is still an issue.

Seems to be a common problem.  Pendragon is the most useless as he gets defeated all the time.
