So let's talk the new patch! (8.2)
I notice some minor HP regeneration adjustments. They're so low..... that I don't know what they're supposed to accomplish, but I'll truth them..
Being made more RIP-y by adding 20 AD damage to each hit of his ult (increasing the rate of how fast he drops a target down for the missing HP % damage)
Major nerf! (My prayers are with you Kat players)
Voracity (Passive) - damage on dagger picked up changed from [75-287 based on level] to [65-220 based on level]
Major BUFF; Q is gaining about 20 AD damage on full build. E is gaining a whopping 60 True damage at full build.
Alpha Strike (Q) cost lowered from 70/80/90/100/110 to 70/75/80/85/90 AD ratio increased from 100% to 110%
Wuju Style (E) True damage increased from 14/23/32/41/50 to 18/26/34/42/50 Active bonus AD ratio increased from 25% to 40%
(Dunno how I feel about this: Champs who are good at baiting and ccing Yi already can almost get erased by a Q mid - late game, which worries me if this will put him over the top and kill those people in one Q).
"The Revert"
Not only is he getting AD scaling based on pure %, he's also getting AP scaling, AND AP scaling on AP Bola Strike; This is going to enable 
builds on a champ that already destroys people.
Unseen Predator (Passive) Bonetooth buff changed from [1/3/7/13/20 flat AD and % bonus AD] to [1/4/9/16/25% bonus AD and AP] Leap distance from target on landing lowered from 100 to 50
Savagery (Q) [Revert/Rework] [New] Active - Rengar’s next attack deals 10/45/80/115/150 (+1.1 TAD) damage [New] Empowered - Rengar’s next attack deals 30-240 (+1.3 TAD) damage and grants + 40% AS for next two attacks Q grants ferocity and Attack Speed vs. towers, but does not deal bonus damage. No longer partial resets after the Q attack (Pressing Q is still a full reset) Particles and sounds have been added/re-added to support the old Q animation and buffs. This includes stuff for skins. Q animation speed has been adjusted to better match when the damage comes out Old icon is back. Empowered Q now consumes ferocity on cast (should fix a number of bugs and feel issues)
Battle Roar (W) AP ratio lowered from .8 to .7
Bola Strike (E) [New] Now has 60% AP ratio
Thrill of the Hunt (R) Range at which enemies can sense Rengar lowered from 2000/3000/4000 to 1600 Range at which Rengar can track the nearest enemy changed from 2000/3000/4000 to 2500/3000/3500 Enemy champions revealed by Thrill of the Hunt (by being closest to Rengar) stay revealed for the spell's duration (even if another enemy moves closer) Movement Speed increased from 40% to 40/50/60% Closest enemy leap bonus changed from providing a critical strike to [gain 3 Ferocity and shred the target's armor by 10/14/18 for 4 seconds.
**
ADC's who go Inspiration are getting nerfed! (Supports too!)
Can no longer pick both Magical Footwear AND Stopwatch! (most will still go Stopwatch so they are losing 10 movement speed!)**
And ofc.... Swain (Oh joy another permaban!)
All in all not a bad patch. I'm kind of uneasy about Yi, and the potential of Rengar, but the rest looks pretty good. And yes. Swain.
