Assassins are worthless
Little to no utility and their damage is almost always concentrated into <2 seconds of nuke damage with
being exception.
Almost always out-performed by divers assuming either class is balanced and not too weak/strong, who also don't primarily exist in mid lane unlike assassins so your team can still have the benefits of a mage (AOE, range, waveclear, CC). Most divers also do it with much less counterplay; why bother playing Zed when Hecarim can run out from fog with Predator and Trinity and wipe your carry with one button and follow up with CC? The only assassin who consistently stays viable is LeBlanc; even Rengar and K6 have quite a history of slinging back and forth between dog shit and broken.
That's not to say assassins should just have CC and the problem is solved, but they should at least have more to justify being picked than lots of concentrated burst and some mobility. Akali is currently the best assassin design in the game with her niche shroud utility letting her be a strong answer to targeted champions (while managing to maintain decent counterplay to it) while being weak into skillshot-heavy enemies.
I've never once said to myself "Thank god we have Katarina on our team."
and
used to be labeled as assassins in the old client for some reason.
has decent waveclear and can still set up picks with the team with E
isn't listed as an assassin but tbh she plays like a ranged
without the stealth when you go lethality, season 6 she was arguably one of the best assassin picks in the game, so she might as well be, she can split pretty effectively and duel a large % of the champs in the game.
has decent waveclear, can engage or peel with W, and can fill a few different roles.
has decent lock down with double chain and her cooldowns are short enough to go for a second target in a team fight.
This one maybe doesn't even count
has some of the most reliable CC in the game
has enough utility to function as a support
probably don't count as assassins
can team fight pretty well, though I'd probably classify him more as a melee ADC, similar to
rather than an assassin
does have a ranged slow and resets so team fighting isn't too bad
under the right circumstances she can team fight just fine and deal more damage than most mages, her thing is mostly just high damage though so it makes sense she wouldn't bring utility.
can reveal stealth and has a hard CC ultimate, even poops out wards all over the map just because of his W
the lemme just kill this one person in particular crew, I can see the point with these ones.
has pick with E, otherwise just there for the burst, a bit of utility with the HP shred and slow
good poke, a heal, traps for vision
basically all cheese, but can annoy the enemy team in fights so he has that going for him
has sustained damage and ult can work as wards, I'm still never thrilled to see him on either team though.
I'm honestly not super sure what this champ even does anymore, but I think they still have the tremor sense and I know the knockup and tunnels are still a thing.
Almost forgot the terror of season 3, not really heavy on the utility, can interrupt channels and slow, but he can do some more consistent damage over the course of a team fight.
