In the past year, Wits has probably been the second hardest nerfed item in the entire game. (DFG takes the prize there, but thats cause it was OP)
By why is Wits being nerfed? It doesnt scale well into lategame as other AS items and nerfing it only further hurt people who utilize on hit builds (WW, Volibear, Irelia, and Udyr, all of whom have seen better days)
Meanwhile you let other AS items that scale incredibly well go untouched. Why? Why do you love AD carries so much and hate on hit builds so badly?
