Being able to make every other weapon broken is irrelevant. Some people want to use the Crossbow without it being leagues ahead of all other ranged combat weapons. The only Crossbows available on the game are better than Daedric quality bows which is where the problem lies. Crossbows have the damage of a Daedric bow and the speed of a Long Bow on top of a built in stagger.
Not using it is only a half assed solution and the end result is a player who wants a balanced game is missing out on content because Bethesda can't be bothered to balance their game. Just because you don't understand gameplay balance doesn't make it nonsense and calling it such doesn't refute an argument.
It wouldn't be hard for Bethesda to make the Steel Crossbow low-mid tier and the Dwemer Crossbow high tier. That way people who want a broken weapon can smith and enchant it all the like and get the same result, while those who want to use a Crossbow without being forced to play on Novice can do so.
Some people do like to walk around on a power trip and I can appreciate that but people need to understand not everyone wants an easy adventure or to roleplay an immortal who one shot kills everything.
An unenchanted dragonbone bow does 20 base damage.
The lowest grade crossbow does 19.
This is by no means enough to one-shot all enemies even on the lowest difficulty level.
So yeah, that it is overpowered is just baloney.
It may become that way, through application of perks, smithing, enchanting and alchemy, but this is wholly a choice.
I prefer to play on normal difficulty level with an Auriel's bow that does 100 base damage, took me a while to tweak things so it would be that way. I enjoy playing like that and its by no means enough damage to one-shot even moderate enemies.
This is the way I like to play, and the game allows me to do that.
You can make an iron dagger that does more damage, if you like, and you can also stick to the base damage.
This is a
choice and the overpowered argument is
baloney, the numbers do not support it.
