armor for carries
if the enemy team is all AD, should your carries build a lot of armor? i mean, i know like your ap carries should get a zhonyas and all, but what about the rest of their items? and what about on adc's?

but i always feel bad getting that against all ad, because i waste the mr, and i think wouldn't something like
just be better?
would also make you slightly "tankier" and deal some bonus damage. Although Randiun isnt bad.
I think
has the best chance of building slightly tanky because 3 items can give him 300-400 AD which is plenty to kill people.
Very rarely do even full AD teams have absolutely zero magic damage whatsoever. Even certain AD assassins have some magic damage in their kit. For example
passive and
passive.
The MR may be slightly wasted, although I'm not sure you'll ever run across a team that truly has no magic damage (it's possible, but difficult), but you're buying it in large part for the passive, which allows you to come back from assassinations or backline dives to keep fighting,
