I dont know if I would personally run with that build, but thats just how I play.
Main reason is there are lot of stuff in it that doesnt help with tanking.
Like no escape, jet speed,
-10 secs on cd on tranq dart doesnt help much either, +3% more endurance for 3 points isnt really worth it in my opinion, but like I said to each his own.
Personally I would go for http://www.torhead.com/skill-calc#301GoGrdorotzZMsb.1
there are 2 points in there that arent allocated they can be spend on what ever
+ dmg on FB, RB or -cd on grapple and FS or +2% in endurance, or extra dmg on railshot.
