Stealth rework and removal of Ability to see stealthed champz

Every time rengar is touched I end up adding an extra ounce of bleach to my cup. I feel like his changes like the duration of his camoflauge and how close he can get before you can spot him is rediculous. I main mid and ADC so my champs are generally squishy. So by the time I see a rengar even without the bonus AD from bonetooth necklace its far too late. Then by the time he targets out tanky top lanes for that final stack its far too late to save the game. I feel like the removal of pink wards ability to give vision to stealthed or camoflauged champs was like giving rengar a double buff this patch. When I heard about the rework I was excited. Hoping for the least bit of counter play. Now you can't even cc him. He basically has a cleanse in his kit. Then invulnerable to cc for 1 second which with rengar is enough time to make me go color blind faster than I can say fuck rengar. I just think the khazix and rengar changes left little to no counter play.
