This doesn't seem like "set" clipping, if you're arguing that the weapons clip with the sets. The weapons aren't considered part of the same armor sets, are they? Plus they give the option to hide sheathed weapons.

The majority of the weapons post level 50(with the exception of trial weapons and a few random ones) are part of an armor set. In the case of the i290 job gear it's even more so apart of it.
