After got lvl 34 to my eating machine gun I see some improvement, but I can't found any reason to use it because proc weapon is very difficult.
For the armor and helmet I don't really found any reason to use it.
Maybe only if the game makes a eating machine only portal (you will enter only if you have the set and use only the set ) with other type of drops maybe some spirit xp packs new pets for more spirit xp.
This type of map is needed to we the players to understand What's the reason of the eating machine equipment?
For what reason they make it? Why is lvl 76?
