Unless it's a SOS/SOM/SOSUN and you are farming at 3X, I'd say don't even waste it. If anything, having a good 38 weapon is way more important since the next weapon comes at 42 and all 38->42 is long grinding and perhaps doing the jewel quests, wine, and so on.
I'd say don't invest so much in a weapon you really won't be using for so long.
