tank in season 14

My friend (a tahm main) keep saying that ADC's and tanks are the one that have been left behind in season 14, he say that both are really weak and new tank items are bad compared to what mage or assasins got. Im making this post because i want to ask you, how would you rank tank on a scale of 1-10 on this season (1 mean unplayable and 10 mean op as f.) I ask the question because he is certain they would be like a 2 this season, meanwhile he always get top damage with toplaners tank and even got a penta on shen tank on our last game.

(btw i cant deny that my friend is a really great toplaner but he keep saying that some top are OP like camille or darius, we keep saying to him that its normal if they do more damage than him since he got a tank and they got combatants, but he stay on the middle of the lane and try to fight them, so i think we can blame him to not be a SO great toplaner on this point, but that only my pov)

(here his op.gg btw : Kench tahm r#2888 - Summoner Stats - League of Legends (op.gg) dont mind the name, its a bad joke in french )
