Adc first items
So I played adc last game, and was told that IE into statik shiv start isn't a good item combo for Cait. Now, I'm a jungle main so I'm pretty unfamiliar with adc builds, but I would like to know for when I have to adc in the future. Should I start BT, or was IE ok? Should I go BT into IE? And any other build tips for adc would be appreciated, if you have the time. Just trying to become a better player, one little piece at a time.
(As a side note, the two adcs I can play fairly well are cait and graves, so I'm mostly only interested in these two)
