I heard about a video of a T6 warrior soloing Ramparts on the PTR, so I decided to do it myself. It was surprisingly easy. It only took me an hour and a stack and a half of food. I died once after I pulled two groups and stupidly left the dogs until last to kill (used Last Stand and the bleed they do killed me once it ran out

)
On to Blood Furnace in the near future!
Edit: FYI, my gear is a mix of Kara, badge and ZA stuff. On the PTR I have 15324 health, 17172...
