Let's make bets that ezreal replaces Tristana next patch.
After about 5 patches now there has been one adc that outshines all the rest in power. How about we go back to the drawing board and make each adc have a special niche.
Vayne: kill, escape Caitlin : kill, escape, place traps after cc for more cc. Tristana : kill, escape, blow up towers Lucian: kill while escaping, repeat Ezreal : escape. Escape Draven : kill, kill Corki: nothing Xayah : free poke, escape Kogmaw : kill, suicide bomber Kalista : the true adc. So true that nobody plays her because nobody actually wants to adc they just want to kill/escape
And the only one that has a niche Quinn: backdoor
(He used to be bot,now he's an ad carry ranged jungler) 
And,obviously 
Traps and long range crits
as i said,magic based spellcaster. I know he's not used bot anymore,but he is considered still "AD Carry"
It should be "extra gold for more snowball",but with how he's been in recent times it can also be "super damage unless you miss your showoff"
Spellcaster Attack based spellcaster + 2nd Safest + Single-target heavy
As you said,the true embodement of "Glass Cannon AD Carry who needs a support in bot lane". Also "No need to smite,i stacked that baron at 256",i guess.
AS based magic damage ADC,or On-hit sometimes
low range Spellcaster duelist that can shoot you down while escaping.
Juggernaut ADC (some people can make it work,and Riot wanted it when they failed it,so technically)
Roam Assassin Burst
1st safest + Hard Push potential + Tower Destroyer + decent magc damage + she once used to be the reset based ADC but now she only has a reset on her W but who cares as long as she is used we won't change it. Yes i'm a bit salty that her only reset is on her W,even if it was for balancing purpose that they removed the E-Q interaction.
TankShredding + Mobility + Chasing victims + 1v5 + how is she able to kill squishies in 2 hits if she is the tankshredder.
Poke(not even that much like others) + Crit and linear CC.
