How is the Adventurer's Critical Ring now that it doesn't add 10% damage?

According to this, the critical ring only seems to give critical chance now and not critical damage. How does that make it stand in comparison with the Cruel Ring? Does the new critical system post-Big Bang affect the choice at all? I'm assuming it's still better, but does this change anything? If it helps, I mostly want to know how it would change (or not change) the decision for Arans and Paladins.
