If you've continued as a mage, I imagine you're probably boosting intelligence a lot more than strength, so you would do better with weapons that primarily do magical damage. The initial class choice determines your starting weapon / skills / stats, but does not restrict you from developing your character however you wish, and once you've gone up a few levels your choice in Farglow no longer matters.
Bleed and the weapon expertise would help, but there may be better places to put your skill points, if the sword is more of a backup.
