Just something to prove that not all the previous expansions had bland weapons. (everything on the right side are WoD weapons but it was cut off a bit.)
Infact, Cata had the most simplistic, and elegant weapon out of them all as the image shows. BC has the most bland. It's very basic with no real design put into it. MoP, contrary to popular belief, had the most unique weapons because of the asian aesthetic which provided for alot of decorative and beautiful gear. The only really gritty expansion was WoTLK and that was mainly with the ICC patch in weapons like Ghoulslicer which invovled too much metal, death skulls, or spikes.
WoD is using the savage look to fit the theme of the expansion for orcs and humans. they do have some nice looking weapons tthough such as that mace, the bow, that shield with the Warsong Clan symbol, and a bunch of other stuff. I'm surprised you guys are ignoring the gems like that. Such a shame.
