I realize a lot of people absolutely disgust vayne but...
to clarify on her change to silver bolts she used to have base dmg+% health dmg now its just % hp dmg with a minimum IT WILL deal
another thing to note vayne she was an adc hit hard by the changes
to(but i don't play kalista so ill leave that to kalista mains)
she got not to much benefit from item changes she basically builds the same as always
BORK got nerfed and the price of
was increased
her base ad was nerfed last patch and without compensation on base ad her ad per lvl is reduced
She ONLY got compensation in form of SILVER BOLTS
if you think about it it does less dmg early,less dmg to squishies(early on atleast) but will do approximately the same as old silver bolts(however i do believe this form of silver bolts does more dmg to tanks)
so don't complain she is stronger then some of the reworked adcs early on you can't complain that omgomgomgomgomg silver bolts early to much dmg early game since its basically been destroyed early game so pick any lane bully and enjoy crushing vayne(till she eventually farms up and kills your ass)
and other lane bullies to a far better extent then now where the tiniest of trade openings vayne can take 15% hp ish
