Riot needs to rework more Tanks/tank items

Just now I faced a garen, I thought he would go Black cleaver into tank, but no, he went triforce, ghostblade, edge of night, infinity edge,warmogs, swifties. I thought that was a dumbass build, but he not only took LESS damage than me. (tank singed with rylais, liandrys, deadmans, tabis, guardian angel, rightous glory.) But he did also did 1100 ALONE with his E, crit me for 1000 with his q and ULTED ME FOR 1300 TRUE DAMAGE. Maokai, garen, zac, darius. "oh but you can kite them right?" (stormraiders garen with swifties and ghost and phage item) "oh but you can also kite darius too" (darius stormraiders, swifties, ghost, and phage item) "maokai can be kited right?" (low cd slows and dashes that root and an insane heal for spamming abilities). You catch my drift right? I feel like utility keystones and items should be nerfed and it should be pretty obvious NOT TO GIVE TANKS TRUE DAMAGE. Irelia can build tank and do damage, im fine with that. But garius and darius are two KEY tanks that should have true damage removed from their kits. I understand "but they arent a problem in higher ELO" But what about lower elo? Its not fun fighting garens and darius' and whatnot. Its not fun to not be able to move and have a darius get almost 300 AD FROM HIS PASSIVE AND ULT YOU FOR 1800 true damage. Something has to be done about this, there is counterplay but when they get fed there has to be counter play and youd think seeing clips of them 1v5ing teams should be enough to nerf them and watching garen q r the adc for 2000 damage.
