What you have there looks good, and if you were two get to Khonsar Rings… < shifty fire eyes >
OA for pets is important. I like to get BoD up to 16/16 for the flat OA it gives pets (you could also use some points in Aspect of the Guardian to get that pet poison resist up, and phys resist is always welcome). Somewhere around 50% OA for pets the critical hits really start to add up. I wouldn’t say you need it more than damage %, but you do need it. Get your current build up to ~60% OA pet bonus as it is and you’ll see big damage improvements, imo.
