User blog comment:Simbey/Real Talk: Rengar/@comment-4652200-20140509113746

I played him a lot after release, when the rework hit I was really excited and the rework is really good after you get used to it.

The only thing bad in the rework was R showing all enemies that Rengar can see from like 2k range, fortunately with his 4.6 R buff ("Stealth alert now only appears if enemies would be able to see Rengar out of stealth.") you can now ult and sneak up on people who aren't brain dead or AFK.
