Rockfall is nature damage, but even so, the amount of damage this glyph would protect you from would be negligible in that situation. Unless you're getting hit directly, in which case you have bigger problems (and relatively it would still be pretty negligible).
Glyph is way too weak to be useful except in a few rare edge cases...
OOC disengage is nice I guess.
Honestly all the items this build has introduced are a lot more interesting than anything in the hunter section (not to pull this off topic...).

Why on earth would anyone want that ever?
