Many have complained about the change in spell system and don't like dual wielding, while others have taken to it. In previous games, casting spells was completely different to wielding weapons, allowing you to have a spell active that you can cast with a separate button. In contrast, Skyrim changed it up to allow you to put one item in each hand, AKA dual wielding, so you can use two spells at once, or one spell and a weapon or shield, but can't use a weapon, shield and a spell at once.
Which do you prefer? Or do you think both are awful and would like a system change?
Personally, I prefer Skyrim's way. If you want to be a full mage, it makes sense to be able to cast multiple spells at once and see yourself casting them. Previous games allowed you to be a full warrior who can cast a spell as a separate thing whenever, without having to really choose. Personally, I'd like a simple system where you can cast more spells at once at the expense of weapons. I don't know how this could work with consoles in mind, but it would make me feel like a proper mage as oppose to a warrior who can cast spells, or having two empty hands but still only being able to cast one spell and have your hands be empty in game. Staves allowed a change in Morrowind and Oblivion, but they are very different to spells.
