Dual wielding spells is awesome!
This thread isn't about dual wielding spells but I tend to disagree that dual wielding spells is "awesome". I was expecting a lot more from dual wielding spells. For starters, we were led to believe that there would be some mixing of magical effects with dual wielding spells, but that turns out to be not the case. Not even if you have the dual cast perk in both schools of magic.
Dual wielding weapons is more like "dual casting" spells anyway, since you can swing both weapons at the same time. You can do a simultaneous dual wield attack or power attack with a mace and a dagger, but you cannot dual cast two different spells, not even from the same school of magic.
On top of that, dual casting spells is magicka inefficient and for the most part doesn't really do all that much. Impact stagger is the notable exception, but impact staggering all your opponents gets old quick. Your dual cast destruction cloak spells are basically the same as single cast but cost twice as much magicks. Probably the best dual cast is in Illusion because you can affect more powerful creatures.
Dual wielding spells is a nice addition, since you can cast say a ward in one hand and a destruction spell in the other, but I was expecting a lot more from the dual cast perk. Not sure that I like dual wielding spells much more than the old system where you could equip a weapon and a spell at the same time with different trigger buttons for each.
