Id like to hear his answer, but id offer that at least there is some counter play in that. In a protracted fight (especially macer) that means that the Swampies AR could be damaged making it less useful at MOB reduction.I dont understand why it being able to get damaged is relevant, perhaps you can elaborate further.
Someone in discord I thinkk mentioned that Swamps have bad mount-stamina. Im not sure if that was in relation to ethereal or other mounts in general. Thats another thing. Its maybe ok to have things that provide some perceived benefit but come with a drawback. If Swampies reduced MOB damage but ran out of stamina after 100secs running then that changes things or at least provides a choice to take the item/gear/mount or whatever. Instead of it being "do i take my overpowered item with me" it changes to "do i take my overpowered thing with me that also creates a weakness for me" its not a 100% always on choice
