I know some of you think that building 
in 
is Thrilling (super Range Headshots).
But with more decisive abilites and AA modifers 
W Stun - 
Empowered Passive - 
Q Attack
All of them with the standard AP Build plus 
I must say something,** it is so horrible and so funny when they understimate the range at which you can totally wreck them.**
It also makes their combos a lot safer and reliable to use.
Friendly Ram1 votesYh an ap version of rapidfire would be hysterical.
Cherysse1 votesTRULY OUTRAGEOUS! seriusly.
It is really good on those champs, sometimes I do not build boots, I just replace it with that item (at the end I get 20% MS from Ludens, Lich and RFC).
khorney1 votesWhat's yh
Friendly Ram1 votesYh yeah yes yep
khorney1 votesPlay boy check this out kass w is a move that will proc lichbane spell blade what ever you get, ludens echo and this rapid fire and static shiv . Nothe to many people can do this
Cherysse1 votesYes but Kass is a Melee Champ, he would only be getting like +60-80 bonus range, it's worth testing anyways, honestly Kass scales really well with crit because his base AD is super high, reason why from time to time I build 
on him (+33 AD late game, +66 when enraged).
khorney1 votesIt's not about the effect of increasing range it's about adding as much damage into 1 w. Basically he is a melee version of ez. You can't add 100 plus instance magic damage on hit unless you have a high amount of it
Cherysse1 votesHmmmm well I think you get more damage in general by building AP on him, but if you want to replace boots I would go with RFC, but in my case it is about adding range, the damage is a real plus of course.
