they buy warmogs, cause there is no ONE item with enough health+MR or with just MR to it IN ONE SINGLE ITEM.

as bruisers and ADCs tend to deal alot of damage even when not fed, you still want to not die in an instant to them, so you need armor or HP as well.

so in the end, ppl end up buying health, as its more costeffective.

if there was a MR item with 90 MR in a single slot, you would sure as hell see people buy it, no matter the price.
