Pure tanks, aka Meatshields, have always been useless in League of Legends. In order for a champion to be a useful tank he / she needs to either have considerable base damage or crowd control and protective skills.

Champions like Nasus, Renekton or Olaf are not strictly considered as "Tanks" but in fact they are: they almost only build armor, magic resistance and health items while retaining their great damage dealing potential.

On the other hand, Alistar, Thresh and Leona offer great ccs, engages or protection thus being good supports.

Pure Tanks are just ignorable during fights and for this reason they are almost useless.
