Boomerangs got hit rather badly by the excessive missile breakage in p23. They seem to have a very high chance of breaking on the first hit.

I get it that they're made of wood, but given that they're so rare, I feel something needs to be done.

(Ceterum censeo arrow breakage needs some tweaking as well, but that's another issue entirely. I mean seriously, even rocks break now... how often does that happen in real life?)
