I just can't understand how it is a house rule. If something says it can be used "as a martial weapon" in a certain circumstance then under that certain circumstance it actually can be used "as a martial weapon" in all cases where martial weapon rules apply.
I'm just going to back out of this though. It is like arguing "Your character class doesn't let you pilot all land vehicles, so you have to learn to drive a stick-shift car in order to proficiently drive an automatic car."
