Oh Vayne

Vayne Thresh Sion Basic attack damage= 0 Armor = 5432525 Health = 3452234355426 Attack speed = 2,500 hit per secund(hit/s) W lv.5 = 12 % of maximum health of the target in true damage

Calcul : Time taken to kill Thresh or Sion(only with basic attacks)

Time taken to kill Thresh or Sion(in secunds(s))=(100/12*3 hits)/(2,5000 hit/s)=10,8 s

100/12 : Fraction on number of 12 enter in 100. 3 hits : cauze it takes 3 hits to make 12%

*** Notice that Sion and Thresh had probably spent many hours to get this large number of stacks, but Vayne just had to get her lv.7... That took probably less time to get this level than to get all the stacks of Sion and Thresh... just to notice too... Also Vayne had a basic attack damage of 0.

The calcul can be generalized for different attack speed : Time taken to kill Thresh or Sion(in secunds(s))=(100/123 hits)/(2,2500 hit/s)=12,0 s Time taken to kill Thresh or Sion(in secunds(s))=(100/123 hits)/(2,0000 hit/s)=13,5 s Time taken to kill Thresh or Sion(in secunds(s))=(100/12*3 hits)/(1,2500 hit/s)=21,6 s

I don't think other champion except Vayne could kill Thresh or Sion in a short delay with that number of stacks of armor and health without any item. Gnar could be another exception, but his maximum health damage is in magic damage, so it would take more time than Vayne to kill Thresh or Sion.

So, her basic attack could be increased or her w damage could be in physical damage to make her more balanced.
