I would make 2 minor changes to the build.
Instead of the 2nd Blessing of the Zephyr in Combat Jumping, I'd put the Kismet +Accuracy IO and in Entangling Arrow, I'd slot an Endoplasm HO instead of just the accuracy.
I would also try to put Defender's Bastion into something other than Oil Slick so that the proc will fire more. You've got a very proc-heavy build, which is not something I'm super familiar with, so I don't want to make any other comments on it.
