If crossbows existed back in Morrowind times, but nobody is using them in the late 3rd and early forth era, surely that would suggest the technology was lost? Crossbows are naturally more practical than the bow and arrow and have major advantages; wouldn't all of Skyrim be using crossbows?
If Dovahkiin is the only one with a crossbow shouldn't he share that technology with the people of Skyrim instead of using it for himself? Bethesda should have incorporated bows into the game from the beginning so all of Skyrims population use them. This would make more sense as the 200 years between Oblivion and Skyrim could have been the time of the "comeback of the crossbow", instead of just sticking it into a DLC.
I just like crossbows and I'm annoyed how they have decided to add them now, when they could have been a major part of the game...
So yeah, they could have handled it better. Rant over
