This is my 9K version of Classified Vampire Striker. It plays the same way, except trades 27% DPS (an increase of 37% in TTK) for 32% more health and 66% more health per second in healing (including an averaging HoK). I personally prefer the 6K version.
You could better optimize this using DtE mods and gain back some of the lost damage. But some form of OCD kicks in for me and dislikes seeing a mix of purple and gold gear mods. Re-rolling everything to Stamina and using a single purple stamina DtE mod with 2 purple firearm DtE mods and 2 HE firearm CHC mods results in a DPS loss of 21.6% (increase TTK by 27.6%) instead.
You could also go for gloves with CHC, CHD and SMG Damage and run a Destructive and Self-Preserved House. The face tanking is extremely powerful in this set up. At full stacks while shooting and hitting you're healing for an about 75K per second. The trade off is that you won't be doing much from range, so you've got to get in close.
