That said though, I was also a tad disappointed because I'm pretty sure weapon drops from Lak could be very aesthetically pleasant.
Maybe in a later patch they will make crafted Lakshmi weapons for glamour purposes, complete with extra shiny "weapon draw" effects like we saw with most HW primals :)
