Nerfs to One Shot squeshies for Rengar are already on PBE
1. Base armor increased to 27.88 from 25.88 The increase in base armour is great to keep him healther in the jungle.
2. When Rengar dashes, he lands slightly short of the target (prevents you from throwing bola over their head). Sounds good, right?
3. Savagery (Q) : Ferocity effect damage lowered to 130% of AD from 150% Ferocity effect Attack damage bonus for 5 seconds increased to 20% from 10% He lost 1/7 of hes Empowered Q demage. So what? I'm pretty sure that with full Armour Penatration Rune Page and Thunderlord, it will be still possible to kill wanted targets almost as fast as before. Jungle clearing speed shouldn't be noticably slower, becouse of the +10% demage buff after using Savergy Q.
4. Bola Strike (E) Cast time added to airborne E instead of instant cast. Bola can now be cast outside of your cast range. Thrill of the Hunt (R) Exclamation mark range notification range increased to 1550 from 1250. While stealth, you will gain movement speed regardless of whether you are moving towards target or not. This means, that rengar won't be able to insta-root and kill hes targets without giving them a chance to react - players will be able to dodge hes normal and Savergy E. Becouse of Increased Exclamation Mark Rengar players will have to sacrifice Ionian Boots and get Boots of Mobility or Boots of Swiftnes as fast as possible or even take some MS Runes, to be able to reach targets. it's a huge nerf for hes early game, becouse of not have enought MS yet and becoue of 10% CDR lose, but feels decent later on.
As a rengar player, I actualy don't like these nerfs/changes, mostly not becouse of the nerf to hes Q, but becouse of the changes to hes E. I'm not saying that rengar didn't deserved any changes/nerfs, becouse of hes current form and increased bann ratio. Probably no one would like to see nerfs to theyr favorite champion/'s, including me, but in my opinion Rengar will be healther with these changes overall.
