Zed and Rengar were both nerfed into oblivion.

Stop saying that ADCs are assassins
Although Tristana is bs

Well two of them are considered secondary assassins.
I've seen Cait with full lethality do a lot with ult, nearly 100-0, but that's about it.
That's an ultimate. Have you ever been killed in 1-2 autoattacks by her or Draven? They aren't Secondary Assassins. What about MF with her Q? Or Jhin with his goddamn Q-AA? I've said this before. Assassins should one-shot, and should be squishy, and have to get right up and close with the enemy (Zed, Talon, Rengar) and have to outplay their enemies to escape a sticky situation. ADCs should deal sustained damage from afar. They shouldn't one-shot with lifesteal and a whole team to protect them, or just auto-attack their way to full health from three enemies in order to escape a fight gone South.
Vayne and Twitch are classified as secondary Assassins. I haven't experienced being 1-2 shot by either of those four, as I'm good at not stepping on traps, and I usually ban Draven every game. The most I've seen is a Vayne 3 shot.
Once I took like 80% from MF Q yes, and I don't like that champion anyways. Jhin, no. I main Jhin and haven't ever 100-0ed someone just by Q-AA. Besides, you can't act like ADCs have a lethality and conventional build in one. MF's Q is the only BS thing I've seen from an ADC. Go play Varus or something and act like you can 1 shot everyone and heal 30% HP per auto, see how well it goes for you.
Bring old rengar back pls.
auto + q + auto makes her the best assassin in this meta with her passive imo.
