That is how Riot wants him to be played because Riots bad at balancing stats and items between classes. Tank items in particular
Maybe ADCs shouldn't be allowed to build
at 2.5 items. Cause that is what he's trying to insta kill.
+400hp
+30armor
+12% auto reduction
Not to mention Ruined King active and lifesteal
Ruined King and Cleaver have nerfs planned and Tabis need them too
I think it's less of an item problem and more that it's unnecessary to build a bit extra damage when baseline defense is so low so you might as well multiply your life expectancy by a large percent if an item allows you to do so at minimum trade off. Maybe everyone in the game needs more hp/level with hybrid offense defense items taking the slight hit
Also it doesn't help they are level 18 with level 18 health with a low amount of items.
Items need to be balanced versus other items.
Champions versus other champions.
Masteries versus the other mastery trees.
You can't have weak tank champions with overpowered mid game items with weak then strong then nerfed to balanced masteries. You can't nerf every on-hit item in the game because there was pre-nerf fervor of battle. Then have "Tank Ekko" abusing both. It's simply just constantly shuffling shit because they won't identify problems individually. Defense itemization has been imbalanced ever since the removal of the original last whisper in preseason 6. The meta game has matured since the early days and its been a constant race of bulkyness wars.
