Lower all AD items AD values. Raise all AD scalings.
Flat out, ADCs and AD characters in general do to much damage with auto attacks for them being point and click. I think that the achievable AD amounts need to be lowered so autos dont do a ton of damage. Seriously 1300 dmg on hit is NOT okay. In exchange, scalings from AD need buffed. Ad should be a small number with huge multipliers. Ap should be a huge number with small multipliers.
are seriously trash early game. adding more scaling wouldn't help, because all they pretty much do all game is scale. plus, ad has always been a lower stat then ap, its the crit plus how fast it can dish out that makes it effective (meaning small with big multipliers)
would always come out on top because he goes true damage and excellent burst anyway (that's literally his forte).
. None of these champions are considered mandatory like the ADC role is. Here's a quote from Riot in Patch 6.4, where they had to basically intervene quicker than they usually would (this was before they hotfixed bad champs the week after they were released):
, Jhin's attack speed will not change. If you buy
, Jhin's attack speed will not change. That is what the phrase 'hard capped' means, it means a number that cannot increase in the normal way because of specific coding made by Riot.

Need sustain?

(+extra burst)


we got that too.
by a tank with 4k health who can out-damage the carry with his abilities' base stats alone?
and OTHER ADC's, who will burst you down much faster than you can.
it's not that easy to ever get enemies clustered long and packed enough to melt them with feathers and E i think.
