Adventurer rings were nerfed again.

I would guess that the extra 5% critical chance allows for slightly more stable damage, and thus leads to higher average DPM over the cruel ring. However, I really can't number crunch even if my life depended on it.

Now that I think about it, considering how Shadow Partner works, I would think that Night Lords would prioritize higher critical rate over critical damage.

Long story short, higher 10% crit + 10% damage is better than 5% crit for 20% damage for all critting classes. Probably for most non-critting too.
