Burst balance in bot lane

Hello fellow people, I'm not sure if you people have been in a game like this but i have, many times to be exact. We knows those burst champion right? examples: Zed, Brand, and Fizz etc. I've been in games where burst champions are in the bot lane, which is very annoying since once they have there ult up or all the cooldowns up. The minute you try to cs they jump up to you and basically eliminate you in just a matter of seconds. These comps are very snowballing and quite annoying. Yes there are champions that are meant to kill the carries etc. but sometimes these champions in the bot lane can cause huge problems such as the team ragging because you fed the burst champions on the enemy team, but you knew you couldn't do anything to stop such a thing. Burst champions > damage over time champions. Us attack damage carry champions are known for their late game damage which is damage over time. While there are champions that uses all there abilities for a combo that is meant to basically 1 shot the person. Putting these champs that burst in bot lane is a horrible idea since now ADC's can't even poke with there comp. One step out of the minion wave and boom you get killed.

Even in late game when the team feed a champion that burst the hell out of 1 person, Once they lock onto there target you're basically done. This makes the game very negative for the players against the comp. So what my solution for this is that ADC's should have at least some time or chance to stop these 1 shot champions. My idea is that all ADC champions should have the damage from the champion that 1 shots reduced or have the damage taken as over time damage. I believe there is a item in preseason which takes damage as over time, but so far these are but the best choices to buy when going against these comps, why? These items lack damage and is more a later on item then a first start. What i'm saying to the point is that ADC's should at least have a chance to stop getting 1 shot, the future of the ADC's are slowly getting weaker since assassin's like fizz or zed can do the equal amount of damage and get in to kill and out without a health bar gone.

So as a example of a game i've played recently. I played Vayne with Karma as support, and on the enemy team is a Brand and Zed. Early game was fine but once they hit level 6 they went all in one us and we couldn't do anything, ganks only came about 1-2 from our team so it didn't help much. Plus we would come out with maybe 1 kill and that's it The Zed and Brand would go with bushes and ambush as since ADC's aren't the most mobile, even a Kalista which is one of the most mobile ADC's can't kite this one out.

Riot please fix the situation with balance you have with assassins. If this doesn't get some attention the future bot lane would be a assassin comp.
