Why yes, I think they are fantastic! I'm also easily annoyed by people saying they are unrealistic and "break the immersion". Guess what, 99% of the stuff you see in any D&D campaign is completely unrealistic. This includes the fact that your characters are allowed to run around with weapons and in armor while not being nobility. Unless one of the party is a noble of some type, every adventuring party would be jailed, and possibly tortured and executed, just for carrying a sword.
