How did you go testing http://www.wowhead.com/item=34427/blackened-naaru-sliver? I noticed simcraft dose not calulate the proc damage (well I couldn't see it anyway) On another interesting note, playing around with gems/enchants for feral showed changing from full agility to a mix of haste and crit boosted dps by around 200-400 pre ilvl multiplier calculations. This was around 4600+ dps to 5000+ dps for reference. Patchwork boss and pre ilvl calculation. I will have to double check but at around 700agility, 25%crit and 30%haste was maxing out dps. Not sure if it is viable to list bis enchants/gems for a spec using the bis gear sets? I realise the stat weights would change for different gear. Just was surprised how much change it made to the overall dps.
