vsommers12: Dorna is my henchmen for traps but she doesnt do that too well. I buff her and my familiar and they do fine enough clearing trash I don't need to cast spells.
Dorna has deeply unfavorable multi-classing. So does Xanos, for that matter. Unless you explicitly tell them to focus on one of their classes to the exclusion of the other, they'll end up just sucking at both.
Sometimes I like to buff myself and start swinging though. Call it role playing but my character has backstory of liking to drink then hitting things with staves.
It's fine to occasionally hit stuff, but you'll never actually be good at it as a Sorcerer. It's not worth sinking a feat into it.
One of the funniest ways to be good in melee as a Sorcerer is to cast stoneskin, death armor, fire shield, and acid sheath. Enemies who hit you have their damage absorbed by stoneskin, then take massive retaliation damage.
