It's absurd that RIot has allowed this to happen for so long. Rengar suffers while Twitch is around.

Honestly I don't know why this has been a thing for almost a year now, it's absolutely absurd and is just a massive "screw you" towards us Rengar mains. I shall explain exactly what I am talking about, but I am quite sure you might already have an idea of what I have on my mind.

Since the assassin update back in 2016 Riot implemented 2 different kinds of stealth. Invisibility and camouflage. Camouflage was given to both Rengar and Twitch, and is basically just pre-assassin rework Evenlynn stealth. The most absurd thing though is that since the reworks Rengar has been almost destroyed through nerfs, and the reason being that he was still too strong when coming from stealth or the fact his early game was too strong. On the other hand Twitch has been left almost completely untouched since then, while still being able to perform oneshots on people (or 5 for that matter). The only thing is that Twitch can do it in a much safer and reliable way, oneshotting entire teams without ever putting himself in danger.

To compare I've gone into practice tool to quickly get a few photos of both's range on their camouflage mechanic.

Twitch

Detection range: approx 500 units https://i.gyazo.com/c141fb0d87918231469b324aad4a84fa.jpg

Attack range with ult: 850 units https://i.gyazo.com/748e316d6f3eb4f3eedff4a9009a7a87.jpg

Rengar

Detection range and attack range: 725 https://i.gyazo.com/b977af69f73bf1052270eb45990fdf34.png

So in short Twitch has a far lower detection range and he can attack from this position with the longest auto attack range in the game. Just to make it even more clear, I'll compare them again in terms of all their strengths.

(Ambush):

• Has 500 detection range which is shorter than his normal auto attack range
• Activates after 1 second
• Gains 10% movement speed increased to 30% if someone is near him that can't see him
• Up to 50% attack speed
• Duration is 10 seconds and can be increased to 14 seconds
• 16 seconds cooldown
• Resets cooldown upon killing an enemy champion
• Gives a potential 850 unit gap between Twitch and his opponent

(Thrill of the Hunt):

• Has 725 detection range and attack range
• Activates after 2 seconds
• Gains 40% movement speed increase at all time
• Duration is 12/16/20 seconds
• 130 seconds cooldown in early ranks
• Gains vision of the nearest enemy within 2000/3000/4000 units and allows Rengar to gain a guaranteed crit if he leaps to them, but also alerts everybody within that radius you're in camouflage.
• Places him in melee range

Quite frankly Twitch has Rengar's ultimate on a basic ability, with potential 0 cd if he gets a kill. He has a shorter detection range and can attack from further away, so he is far safer than Rengar that even has to go into melee range. He doesn't alert the enemy at all, and he naturally builds critical strike so Rengar doesn't even have an advantage on that part, who has to work for it to get it on the right target while Twitch just right clicks and crits 5 people.
