No, I think that's in 4e design. Healing Surges are a resource to be managed.

Consider the amount of monsters that get to eat a healing surge. Wights, and several of the oozes in Open Grave off the top of my head.

I haven't read into the Open Grave material too much. It sounds like I would like it though!
