ADCs now have to support themselves because the support didn't like being a support
The top ADCs it seems all have either hard cc or some form of camo/invis function. ADC now seems to have to protect themselves while the support just looks to deal damage. But since they are AP champs usually, they have better range, mobility, and early game damage to where the ADC usually has to really try to get that last hit for the kill gold (and usually they take some CS too).
Look at the pro games. We have Jhin, Varus, and ASHE as the top 3 ADCs it seems. ANd their supports? MF, Zyra, Malz. High damage dealers who end up taking all the kills.
sup then. I always take it after getting the book.
