No you cant. And no it added quite alot, 26 new perks, 8 new sets of Armour, 5 new weapons, a bunch of new side quests, new random encounters, a large amount of new weapons, a large amount of new creatures, new random encounters , 2 large new areas, and a bunch of other sutff.
The new perks are tacked on, the new armor is useless, the new weapons are almost all worse than what we already have except the dragon bone weapons which should have been there from the start, the side quests are almost all fetch quests, the new enemies are almost all just reskins, the two new areas are empty and pointless.
