Yes and they are going to change that in Tank roster, well Darius and divers considered Different than tanks
Darius is a juggernaut, you can build almost anything on juggernaut no one will look at that, why? because they are the juggernauts, they can handle almost any sort of build and that's their role.
Divers are Semi fighters semi tanks but have ability to dive in teamworks, can also be built damage and some tanks.
But Mundo is considered Tank, they will no longer make the option of IE to overpower your E in the best situation,well it will still benefit it but no longer in tank in roster, Riot themselves told us, They'll make Tanks unique and different than anyone else, they'll have a unique build path and they'll remove as much as they can the idea of full "damage items build on tanks".
And yes back to what i wrote, we knew already that if you are lucian even if you see a strong tank item costs 3800 you'll still go for IE because it's your main role and it benefits you so well than tank build on lucian.
Same thing will happen to Tanks in Tank roster, Ie will benefit but small benefit but for example an incoming new Tank item that's almost same price to Ie , when Tank users build it they'll benefit themselves Massively more than anyone else and people will be almost forced to build it than damage item same as when lucian goes for Ie than tank item, that what will happen exactly.
Back to darius as a juggernaut, there is literally no main build for Juggernauts, Riot also said that Juggernauts considered as a very unique type of Fighters, if you build them full tank, they will benefit, if build them tank ad or ad or or tank + attack speed they will still benefit from it. They will keep that idea of giving juggernauts more optional build in tank roster.
if you are a darius and you have 2 options for item costs 3000, would you go for Cleaver or a tank item costs 3000?
well you can choose any, why? because you are a juggernaut and indeed we can not blame what juggernauts build.
