New slot for Pink Ward

Hey guys , i sugest to add new slot for pink ward (Only pink ward , not another items), beacause in late game you are full build, you haven t slot for it , so , will be hard to counter champions like a Vayne , Evelynn , Kha Zix (...) so , if you can buy pink ward in early , you should can buy pink ward in late too , this small and cheap item can change the game , so he should can be buy all time , not only in 0-40 min. Thank you for attention.
