Basically, 15% isn't high enough of a chance to statistically outweigh the lower base cost of Quick Knock. Over the course of, say, 10 GCDs, even if you get the 1 proc you can reasonably expect (it's only a 1/7 chance, after all), you're still going to burn more TP with Wide Volley + proc than you would using Quick Knock 10 times. Meanwhile, the proc is less damage, too. It's only if you get lucky with procs that you start actually saving TP.
