That sounds like it might be an item imbalance.... that'd be something to post on Mantis. The items arent my realm of design, so I cant fix those. Nor do I know how most of them work, haha. I've not played around with the Crippling Drone myself yet.
That being said, I've boosted the Warden's HP again. And the HP of.... most bosses. I'm going to get this right sooner or later.
