The top played assassins no longer fall off anymore.
Assassins- a class who is famous for snowballing games out off of small leads. They are a class who offer little to no utility for their team. However, they no longer fall off like they should. Here are some stats taken from op.gg that show the top 3 picked assassins winrate by game length, as well as twisted fate's for comparison.
Why twisted fate? He should play out similar to assassins, as he relies on roaming to create leads and using those to snowball. Twisted fate still has some utility late game with his gold card stun, so while he should fall off he should not fall of as extremely as assassins do. However, as shown by the link given, he falls off while the three assassins listed do not fall off anywhere near the amount he does.
Why am I complaining? Whenever you play against assassins, a lot of people give you the advice to just not feed them, they won't be able to snowball, and they'll be useless. Hell, there's even the whole LB win lane lose game meme because that used to be her counterplay. However, now for whatever reason the top played assassins do not fall off late game. Fizz is a slight exception here, because some champions can abuse his early game(which isn't even that weak anymore due to electocute's all in potential). Anyways, back on topic, the counterplay used to be simply play safe in lane, make sure they don't roam for free, and you'll win the game because you will scale better than them. That doesn't work anymore as they don't fall off very hard anymore. This essentially means that there is no stage of the game where they are actually weak. In my opinion, riot needs to look in to this, as assassins should not be strong early, mid, and late game off of only their damage. They need to either have a longer period in which they need to ramp up(generally accomplished by lower base damages[THIS INCLUDES ELECTROCUTE] and higher scaling) or they need to fall off (higher base damages and lower scaling, as well as increased cooldowns on their safety nets late game).
And no, I don't want to make them useless early or useless late. I just want them to be slightly weaker early or late, matching something like talon's curve for winrate by game duration.
INB4 "just pick x into them, just build x" Yes, I know all about their counterpicks and items that help mitigate their burst. I'm not saying they have no weak matchups, i'm saying they're too strong at every point in the game as a whole. Besides, i'm not the only person on my team. They can always delete someone else on my team then escape to safety.
