Try an arial that practices no defenses except dodge. You'll find that arial doesn't rely as heavily on dodge as you think. Obviously it's their best defense, but it's not as god like as all their defenses put together.
I know two people that tried that to maximize concealed usage and both were frustrated with the lack of tankiness.
Then I also add that dodge is the last defense checked. Meaning dance gets used even less.
Your two links, general knowledge, and the wiki is where I pulled the info from. When I said double dodge attempts I just meant it's a second attempt, not that it necessarily fires on every fail (Though I admit I see why/how that's misleading and was wrong choice of words). I assumed it didn't, though Daevryn in those links seems to be saying it's pretty close. I would have guessed more like 50% with the performance of ward on 23 str human.
