So everyone knows about the iron dagger exploit but since they've added arrow crafting I noticed another maybe other people have to but you can smith iron arrows or any kind just with ingots and firewood which firewood is free unlike leather strips and iron arrows yield more xp to the next smithing level than the dagger exploit too

I got lost in the grammar....so are you saying that iron arrows function better than the iron daggers used to be?

When leveling smithing yes they do

Can you now craft all types of arrows? Not just dragonbone arrows?

Yep. All types of arrows are craftable.

Yes.
