I'll C&P what I said in the other thread about this:
BMP weapons are easier and cheaper to get than weapons crafted in towns. They only really have novelty value. After the initial hours of thinking "whoa, these are so cool... best skins yet!" I eventually calmed down and didn't actually replace any of my current weapons (except one plain wooden flatbow I use for pulling. had to use the book for something).
The weapons are free & have no value. People want things ingame that have value, therefore after the novelty of the BMP weapons wears off very few people will still be using them as they're cheap and common.
Cheap/Common items don't really have a place in HoM as it's not an achievement.
As for people asking to allow more weapons into HoM... why would you want to give yourself even more work to fill out your HoM? I've no idea why people would want to make things more difficult for themselves. I'm already putting off filling it as my main doesn't have much use for all 10 destroyer weapon skins. Just be glad it's only 10 weapons you have to put in there to gain the maximum benefit from it.
at this point i am not concerned about weapons going into HoM..till i find out what benefit they will have in GW2 if any..besides i am expecting a whole new line of weapon skins available in GW2..so current weapons wont be so attractive in GW2..just my opinion on matter..
