I'm meaning they didn't have a large selection of Crossbows as far as smithing and having a wider ranger of options.
It would have been nice to have been able to choose between an Ebony Crossbow and a Daedric one. Instead we're stuck with a Steel or Dwarven design. Still, with a max smithing skill with all perks fortified by enchanting and alchemy. The bow intself in general still out ranks the cross bow in so many ways.
Maybe in future games. I would like to see a wider selection in cross bows.
