I love it. Finish up that skinning and grab an int trinket eventually to replace your insignia.
Other than that I'd probably use the satchel crit belt. You could swap that in for this set for moar crit, or use Serpent/Gold Flecked Gloves alongside it to pick up 6 stam at the cost of 1 crit.
Its great though, <3 glass cannon builds.
