Problem with assassins
So assassins got reworked in the pre-season and it was quite fun actually , some of them were buffed , others became unplayable ( R.i.P Shaco ) and some are impossible to balance but this is why assassins are pretty useless :
They are made to be assassins but they are not
Every assassin in league has a unique way of going in eliminating someone and bursting them down , but THEY HAVE NO WAY OF GETTING OUT , You either jump to the backline , kill their adc alone and die to the other 5 , which is not worth , or waste your flash or ulti , and here are some assassins i think that they offer no escape after an assassination
Talon : Needs a nearby wall to escape and he probably used it to go in / he needs to use his ult in order to get out , unless he used his ult to begin with and used a nearby wall if he could
Rengar : he only can flash and that is it
Ekko : He needs to R out of the situation therefore wasting alot of aoe damage in a teamfight
Kha'Zix : if you do not have your E evolved , or your ulti evolved , you will have a bad time getting out of there because no reset on his E and his ult lasts less when not evolved
Shaco : No form of escape if you use your Ult or Q to engage
Etc.
the only assassin's i feel like they are assassin's are fizz and LB , LB has her W get in there burst someone down and use it again to hop out of there , and basically she does not need to flash to get out of there
Fizz : has his E and can Dash with his Q through a target
and an picking an assassin is not worth , since you can pick a fighter and still do tons of damage and survive the entire fight , they feel useless and even if assassin's got over fed , and got 3 lethality items which gives 54 armor shred , can be easily countered as an adc or someone who is ad by a simple Ninja tabi which gives 30ARMOR and a bonsu 10% dmg reduction , buy a ga late game , still get tons of ad and 40 armor that is 70 against 54 armor shred and even with full lethality runes , they would get around 75 lethality max . and basically they shred nothing at all and even a full item assassin for example . a talon with 3 lethality items a boot a cleaver and an LDR/MORTAL REMINDER can't do shit because assassins fall of soooo hard at late game , plus the peel of a strong support is helpful , so basically its high risk NO reward
and rengar alone is impossible to balance cuz he is made to one shot someone , but getting one shotted is not fun at all , and they keep nerfing him to the point where he is unplayable and does not do a single one shot all game at all , or buff him so hard that he becomes first pick first ban every game which sucks for him .
