By the time you have another two fireballs ready, ehich should take aout 2-3 seconds, the sword have added another 144-216 damage.
Plus I have a Draugr Greatsword that does well over 100 points of damage, without any enchantments on the weapon or me that add to damage, just from smithing and having a 99 in 2 hand
I have a glass 1 hand sword that does well over 80 damage per swing, and at the same time, I'm casting a destruction spell with the other hand, on another character. That other character can also dual wield two glass swords that do over 80 damage each
DPS can be pretty high for a warrior. But you need to be close to your target
