You get more offense but the tradeoff is no defense.
I'm assuming if you have a sword and a spell equiped, you will not be able to block also since the left trigger would be the spell.
I still plan to block if i can pull it off though. My plan is to hotkey the spell sword combo, then hotkey the same sword with no spell so its just the sword by itself with nothing in the left hand. We should be able to switch from spell to no spell pretty fast, so if an enemy gets near my i plan on putting my spell away so i can block.
What do you guys think of this strategy?
