I agree - I also have the +def enchants on my chest and back to keep myself uncritable - that is >415. these enchants are not even in the list of possible enchants for a druid.
I think it is unfair we get marked down for this. It is so hard to maintain this level of defense as each time we get an upgrade of an item we tend to lose defense and then we are in the crap again. I am hanging out for the staff from SSC but know as soon as I get it I lose the defense I am getting from my Earthwarden. Then I am back at square one.
I think your stats and points are biased to kitty - dps and need to take into account tanking bear druids.
