I use this ability quite a lot. Ever since the June patch the number of Stunning Kick XXX procs has decreased a LOT (I have a GINA trigger for it, Gamparse doesn't detect it as it doesn't show as an actual spell). It used to fire 2-4 times a minute. Now it's 1 proc every 3-4 minutes. Monk Dex is sitting at 4164. Was this intentional?
Also the proc on the Monk Epic 2.0 - noticed both have had stun functionality either removed or reduced significantly.
