I have the envy rim up front laced 36h/3x
It does the exact same thing coming off at an angle from the rim
Have not experienced a single problem with spoke breakage nor rim weakness
This is after hundreds of whoppers/tailwhips, cliffhanger turbines and many hard carving very leaned over rolling/spinning tricks
The rim is fantastic and I am very happy with it. I probably wouldn't run it on the rear just because of all the whoppers I do but it does great on the front. (Rhynolite XL is perfect on the rear due to the more robust construction).
One advantage to having the bend in the spokes is a little more flexibility and springiness to avoid spoke breakage or even worse, flange breakage on the hub.
