I don't like how similar champion kits still are

and it seems to have gotten worse with the subclasses that Riot deliberately injects champions with a lot of the same or very similar tools and strengths/weaknesses. it kind of just feels like the game's blending in to be too similar and we aren't sure why there's a lack of real diversity. And I don't mean, like, diversity of champions, but playstyles. Champion diversity really isn't that difficult when most of them play/feel the same; when part of a subclass is good it usually stands to reason that the rest of them are at least decent, even if they're overshadowed. But that's also one of the biggest problems; even if the lesser champions are still good or playable, there's no reason to actually play them because a champion with marginally different tools is just objectively better, either by having directly stronger tools or having a much easier time actually putting them to good use

divers, enchanters, marksmen and vanguards, even a lot of mages all seem to struggle with this problem

juggernauts and wardens manage to be unique even if I still personally feel Riot's a bit stingy with them

how do you feel about this? I would like to see more unique, defining strengths rather than marginal variances of samey kits.
