Of all the LoL classes that exist the one that I anticipate the most to be updated...
...are assasins. Let's be honest, there are a lot of issues when it comes to this class, from champions who's design is far from perfect to the problem of AD assasin itemization (or a lack of it).
But the biggest thing I anticipate is rework of few of the assasin champions. My biggest pretenders who are in need of it are Akali, Fizz and LeBlanc (others probably need changes too, but these 3 are my biggest candidates to get rework).
So, why I think these three should get rework?. Well, I'll talk briefly about each of them: Akali - one of low elo stomp champions, also, pretty feast or famine. Either she lanes against a potato, get fed and proceed to get pentas, or she will lane against more smart opponent, safely farm for Gunblade and still proceed to murder everybody's ass (probably adc's ass, they nearly never look at pings about enemy missing, at least in bronze and silver) or she will play like sh*t, feed and will be completely useless for her team. Let's be honest, there are a lot of problems when it comes to her design. Fizz - huge damage and very reliable escape. What else to say, his E is what makes him broken. Great for engage, escaping and, of course, dodging everything in existence. Also, has quite low cooldown.But the worst part is that it is his iconic ability, so not eveybody would be fond of if Riot just decided to take it away. If he ever will be getting reworked (I hope), he's probably gonna be hard nut to crack. LeBlanc - "lvl 2 power spike" - I saw such banners held by people on SKT T1 matches on the Worlds and they describe LeBlanc pretty accurately. She walks to you, Q-W you and bam - half of your health gone, while you have very minimal time to react and retaliate, because of her blink. Who likes that?
Now, I know that there is counterplay to them, as well as they have a lot of weaknesses, but I wanted to adress problems, which, imo, qualify those guys for at least small reworks. They are not fun to play against, they have some toxic mechanics attached to themselves. You might not agree with me, and that's fine. Maybe you think other champions are in need of rework, if so, feel free to share your opinions. But personally, I hope that assasins will be the next group to be adressed after mages.
