[GAMEPLAY] Rengar's Ultimate does not guarantee 100% crit chance

Played over 500 games with new Rengar, have noticed that only about 20% of Thrill of the Hunts I use end up providing the critical strike. This could be a bigger bug within your critical strike system which I know is severely flawed (your incremental distribution calculation at least). Since I always purchase infinity edge on rengar and generally experience this issue when I have more than 0 critical strike, the issue may lie within the way the critical strike is calculated. I would provide a video but since its so easy to replicate, you can probably do it. This has lost me several close teamfights and I have already seen this bug occur on various livestreams / small tournaments.
