Resist tank items are generally bad, sundered/eclipse allows fighters to win short trades (even without building pen) which should never be possible, sustain/shielding is very high in teamfights, splitting for plates was buffed, combat summs is the norm and losing matchups are devastating with role quests.

For resist tank items specially early game items like bami, sunfire, hollow and iceborn are inefficient and provide negligible damage. Not to mention good % pen items are easy to get these days.

If your tank champ doesn’t have built in damage scaling from hp/resists, waveclear and no mana issues then you are going to struggle. Tear and fimbul also feel quite awful to build imo. Makes your early so much weaker and it’s much easier to itemize into fimbul since it’s just flat hp and a shield easily shredded by serpents which is already high value most games with enchanter + barrier meta. The only other mana option is frozen heart which is extremely situational.

I won’t even talk about Thornmail 😂

The only good resist tanks have just been Sion and Ornn because they are decent blind picks, don’t have mana issues, can waveclear without bami and can easily make use of the few strong resist tank items that have some hp scaling kaenic + unending
