That requires a specific combination of characters as well as leveling up a horrible skill to rank 5 first, requiring level 9, rather than being an innate passive from the start. By that point you've already missed out on a huge amount of bonus gold from CS, and are going to get demolished in laning phase. And that's not all Kat's proposed passive even does, it still retains the old effect and gives a bit of CDR too.
