I don't know whether this is a problem on other first ages but my captains greatsword's (75) sheath is too long. The beleriand glow is longer than the blade.
I don't know whether the devs know this or not but fix it soon please, kinda annoying.
I was looking at some screenshots the other day and saw a big 2h sword with the same problem, the glow was a tad longer than the sword. So you're not the only one.
