ADCs feel way too bursty

It used to be that ADCs were sustained damage in fights. Mostly to smack away on the tanky champs on the enemy front line. Now they kind of feel like they burst people as quick as assassins (go ahead and get caught out by a shiv/ie Vayne). And I think the reason why is because they added damage onto everything.

See, there is supposed to be a cool balance thing where Assassins > ADC > Tanks > Assassins. But there was a point where tanks were weak and assassins were killing everything *cough zed cough*. I think we all remember where the team that got Zed one. It was annoying. So what did they do? Added damage to tanks. And when I say tanks, I'm included all those goofy words that you guys like to use, vanguard, diver, fighter, tank, etc. By way of items, etc. Well then ADCs couldn't as effectively kill those champions. So they added more damage to ADCs! Yay! Most recently, we went through a phase where assassins are useless, except a select few. Why? Because ADCs can just burst people.

Basically, what I'm trying to say is, stop throwing damage on everyfuckingthing. Just look at the whole knew masteries system. Basically damage, damage, and tankydamage. People say, "adc in 2k17 lul", but it has nothing to do with ADCs being weak. It has to do with tanky champs just being able to dive through your team and nuke your backline....because everything got damage added on. I mean seriously, release Ekko has more damage in his kit than Veigar does. Makes no sense considering how much other shit Ekko has built in. And then rito wondered why Ekko was batshit crazy.

Tl;dr: If you could stop throwing damage on everything, that'd be great.
