Yeah, I think I'm also using this build.
Basically, it seems like a no brainer to get all of the healing-related Sawbones talents, and then grab the boosts from Scrapper and Dirty Fighting, leaving you four points to choose two of the following: Scar Tissue, Sedatives, Scramble, Med Screen, or Dirty Escape.
Although I plan to PvE primarily, Dirty Escape looks like it could help on those occasions when there's an aggro management error.
