I got an even lower value for crit with my druid, something around 22 agi, but that is with all the feral talents which increase stats included.
And yes, stacking str/agi is way more beneficial for a druid than ratings or straight AP, 12 agi on cloak enchant gives a druid more dodge than 12 dodge rating enchant for example :P Still, the best feral items are not the ones with just str, agi, sta but the really rare ones which got a bit of AP or ratings added to the stats. For example
