One simple question for Riot: Assassin's and Marksmen's interaction (after assassin's rework)

Since you are reworking all the best assassins from the game because they are to "forgiving" and can kill a squishy in short period of time with half effort and "half" of their kits, have you thought about their interaction with marksmans such are Vayne, Lucian, Tristana, Caitlyn, etc.?

Let me mention, I am assassin jungle main and marksman main so there's no bias, I like them both but how do you think that Rengar who is going do deal his damage in longer peropd of time be able to kill Vayne whos gonna stealth, tumble, condemn and literally 3 shoot him? You mentioned that you are reworking assassins so they need MORE SKILL and more THINKING of when and how to engage on someone while adc can still dash out of Rengar's/Kha'Zix's leap, crit for 800-1000, lifesteal out of that insane crit like there's no tomorrow and literally 3 shoot a squishy assassin? Or you are planning to remove assassin as a rome and turn them into divers or assassin like Fighters like Diana, Elise, Evelyn, Lee Sin, etc?

It is a simple question. As an assassin, why should I be forced to execute my combo PERFECTLY and calculate EVERYTHING the best I can in order to kill someone who can dash away from me and right click me to the death with close to no effort considering that both, Rengar, Kha'Zix and Talon are melee assassins. NOT.....NOT to mention that Yoummu's is still viable for ranged champions so there goes MS buff into account.
