Is there any kind of guide to the most commonly seen key items for the different archetypes of hero? Maybe (ideally) with some kind of "for dummies" analogous brief comparison? Like I saw something that is obviously the equivalent of Spirit Visage from League of Legends.

also/alternatively how old is it possible for an article to be before it is completely, *completely* outdated? Like do most of the items still hold true in essence to the last major patch that came with the shop update or whatever a couple months ago? Seems like the last big slough of articles was from 2~ months ago.
