I started a new 2H Orc character and I can't decide on what weapon to use. I know the basics that war hammers have the most damage and greatswords are the fastest. So what do you think is best and why? Maybe some lore on what suits orcs better idk.. Thanks.
If you are going for the realistic answer, battle axes make the most sense based upon your location in the world.
Skyrim is a land based off of the Nordic regions of Europe. The characters are also based off of Vikings / Picts.
Axes would have been the most common, popular and plentiful weapon around.
If you are wanting a practical answer, for damage output and ratio to swing speed, I would still stick with battle axes, as the damage and swing speed are typically balanced.
If you don't mind spoilers, check the wiki for artifact 2H weapons / upgraded 2H weapons to plan which one you want to try to make your favorite.
