In the same way that there is itemization vs silences, there should be significant itemization against immobilize (and immobilize-like effects) available to players, it can be a shoe slot if you need the slot to be a sacrifice in some way. 

A few such examples off the top of my head could be:

-Heron feather like example that lowers immobilize/frozen/clumsy duration by 1 turn
-Shoes that give you a way to break immobilize/clumsy for 1m
-Torso item slot that makes you immune to immobilization (Like Braveheart)

I think Kameron brought this point up a very long time ago but I still think it relevant enough to bring up again still. If you want my opinion, a heron feather-like effect against immobilization results in faster builds having a leg up on immobilization spam, such as with Tentacles, soaked + ice damage etc.
