How could you possibly put Lydia at #4. She has nothing interesting to say, bugs out majorly and disappears frequently and dies easily. She occasionally takes out bandits pretty effectively but those enemies are easy anyway. Lydia doesn't even level and won’t wear light armor so she can’t carry as much as other characters. It’s also incredibly annoying to hear her say “I’m sworn to carry your burdens” with a valley-girl tonality. J’Zargo and Erandur are hands down better than her. The redguard house carl from Falkreath deserves to be on this list more than Lydia. Lydia is my sacrifice to Boethiah.
