What was the design reason behind the Rathalos Armor Set?

[Rockette]

Add in a dismemberment of a body part where you can actually see the bone, muscle, connective tissue, etc., would probably bump up the Animated Blood to Blood and Gore (which is for the depiction of the mutilation of body parts), which could be enough to take it from T to M on top of everything else.

Assuming it wasn't a joke that got lost in translation.

Maybe I'm remembering this wrong but didn't a main story character GET HIS ARM CUT OFF?

Mind you I suppose they hid the gore.
