Why Rengar is unplayable.
Hi, I'm MsKatlyn, Im currently Gold 2 one tricking Rengar all the way up the ladder, Ive been playing him for over 4 years now, and I've loved every bit of this champion, he's just so much fun and requires mechanics, (talking old Rengar.)
This new Rengar isn't fun at all, it actually feels like I'm playing Azir because of how many nerfs Riot has thrown at Rengar.
At start of Season 7, Rengar was considered broken, so Riot basically said, "Fuck our design to his W, lets remove the CC immunity and nerf his dash on his clunky q, then lets gut his ult because we didn't do that before." 7.3 Patch;
[Q] Savagery : Dash distance 200-150
[W] Battle Roar: (Empowered) No longer gives CC Immunity for 1.5 seconds
[R] Thrill of the Hunt: CAMOUFLAGE DURATION: 14/22/30 seconds ⇒ 12/16/20 seconds
Rengar wasn't really dead after these nerfs, he just still didn't feel right to play, actually, let me reiterate; He wasn't fun anymore.
These nerfs were suppose to hit his team fighting ability and getting outta fights with his [W]. I don't know why Riot tried to enforce us with this new empowered Battle Roar, Ghostcrawler said in an interview that they're pushing his direction into Bruiser, instead of an Assassin.
7.5 Patch;
BASE ARMOR: 25.88 ⇒ 22 [W] Battle Roar: GRAY HEALTH CONVERSION: 100% monster damage taken ⇒ 75% monster damage taken
Riot nerfs his clear, making it harder to him fight duelist early like Lee Sin or Elise, this actually was the nerf that hurt him the most. His clear, but now his clear is even worst with the percentage being at 50%.
7.7 Patch:
[Q] Savagery: DAMAGE PER STRIKE: 35/55/75/95/115 ⇒ 25/45/65/85/105 (empowered damage unchanged) RATIO PER STRIKE: 0.3/0.4/0.5/0.6/0.7 bonus attack damage ⇒ 0.2/0.3/0.4/0.5/0.6 bonus attack damage (empowered damage unchanged)
Their was also passive nerfs, making his base AD scaling from his unique kills lowered. These nerfs really gutted this champion, wasn't the whole point of this rework was to make him an assassin? I have to dominate early or I'll be useless with this new Rengar.
Please Riot, you have basically killed Rengar. He's sitting on a whopping 44.19% Win rate, 
If Rengar is so unhealty, why can't you scrap his kit and design and make a whole completely new design, giving him more tools to use at a lower damage window, making it easier for players to react.
For example, Rengar falls in the category of useless or viable. A Rengar player may feel like he doesn't have a enough tools for the hunt, jumps in doesn't get the kill and now feels useless.
Or Rengar jumps in, gets the kill to quick and now theres a balance issue, resulting in nerfs or changes.
I really want my champion back, Ive always wanted to hit diamond with him but with this new Rengar I think I'll let it slide.
