"Actual current meta in a nutshell"
Whatever the fuck you want top.
Whatever the fuck you want jungle.
Whatever the fuck you want mid.
Whatever the fuck you want ADC.
Whatever the fuck you want support.
It's solo queue. Just go look at pick rates and you can see that half this is invalid.
If you want to consider Gnar a tank, he's the 4th pick rate top. If you want to consider him a bruiser, Sion is the most picked tank top lane at 7th. You go past that and you have Nasus (again, more of a bruiser than tank) at 10, and then Shen, Maokai, Ornn at 13,14,15 respectively. Cool, "Tanks that can perma CC you" we have 3 that can CC chain you, because again; one of the 4 tanks is Shen who has 1 cc on a long CD.
If you want to look at jungle a lot of great jungle clear times are low down where as better gankers are high up. Still within the top 15 picked it's a huge variance. You have great gankers with meh clears, great clearers with meh ganks, and everywhere in between.
Kassadin is the second most picked mid laner. You wanna tell me he is a wave clear bot? What about Katarina? Fizz? Yasuo? I'll let you make arguments that corki is afk wave clear, and hell, I'll even throw in ZED as an afk wave clear for the sake of your argument. That's already 4 champs who want to fight and not wave clear. That's not including the pokers like Zoe, Xerath. and Azir who will force to play on your toes.
Since ADC is such a small pool, we'll pull the top 8. We've got: Good early who falls off harder than pantheon late, we got an on hit utility adc, we have Vayne, we have a short range, ZERO MOBILITY adc, we have 2 long range adcs with self peel, and then we have two more of the shortest range adcs in the game with Lucian and Sivir who gives up a lot of power for utility.
Support has 7 supports who are amazing engagers while being tanky, and 10 total GOOD engagers in the top 15. We have 5 "Enchanters", most of them below the top 10, and we have 3 who are pretty bad at peel because of how much they need to engage/follow up on engage.
