Why is ZZ'rot so underated?

Many other items are more useful.

its uselss. I once used 3 and the enemy had no trouble pushing through. its not useful at all. sorry. I'd pick it up for armor and MR. but guardian angel is a better option.

I went against a TF that rushed that item recently. It succeeded in annoying the living fuck out of me when I tried to cs, but it didn't do anything to help him not get slaughtered by me.

it feels problematic to fit into a build. if you pick it up youd get it as third item or something, because in lane you want to focus on health and 1 resistance type instead of an item that splits its focus between armor and mr.

and by the time you finish it it becomes almost irrelevant, as the game is almost over. youre either already winning in which case the additional pushing isnt as important, or youre still working on more important items.

Buying items that have stats delays pushing even more.
