How is vayne anywhere close to balanced? its like a champ from another game or something

Here are her raw stats at level 18 with full crit build + ldr + rageblade + botrk

Attack damage: 301.12 Attack range: 550 Attackspeed: 2.06 Crit: 75% Life Steal: 12% Raw DPS: 620.37

So, shes doing two autos every second. 1.5 seconds to proc truesilver bolts.

On champs without any defensive items:

Approx 500-600 damage first two autos, assuming crits, followed by 500-600 + 24% freaking max hp TRUE damage on the third.

She will kill any squishy within 1.5 seconds or within 3 bolts guaranteed.

Tanks? Assuming the enemy team is balanced as has some magic damage and you had to get at least one MR item, your still going to die in just a few seconds.

All this is during her ult which resets with kills, gives short CD repositioning with a full 1 second invisibility, and her ability to self peel or even stun (which no other adc has).

Two busted mechanics with no counterplay or counterbuild whatsoever (resetting 1 sec invis and 24% maxhp true damage on every third auto), high MS from passive and ult, a stun which is the hardest CC in the game and a full 1.5 second stun.

This champion makes 0 sense in this game. Why does a single champion get such an overloaded kit with no counterplay? And how long has she had this? how can one trust the sanity of riot dev team when they allow this kit to exist for so many years?

And her AA range might not be cait or trists, but its not low by any margin, its quite average for an rADC.

She needs:

Lowest range of any ADC so that she is forced to use invis and repositioning and condemn to last in a fight, invis should be microinvis just to make her untargetable, like 0.1-0.2 seconds, and her silver bolts need to do like 8% maxhp true damage or something.

'Must be low elo hurr durr not meta right now' yeah whatever, this kit is straight up busted and everyone knows it.
