So I waited to do the companion quest's, I'm now level 48 and playing a sneak character. Draugr deathlords I can deal with easy with sneak, but farkas keeps [censored] it up, so irritating, and when I'm sneaking he doesn't fight back he just follows me dieing.
Sorry for the necro, but I see it as waste to start a new thread on a subject that already exist.
Farkas was some braniacs idea to make things more difficult for the player, I certainly cannot think of any other reason, he is forcefully paired with the player, enemies rip through his armour like it's tissue paper, he constantly leads the enemies to you when you are stealthed, I watched him take on another 2h, the enemy 2h took him down in 3 swings.
So my conclusion is, no matter your play style, Farkas is forced on the player purposely to make things more difficult.
