Anyone know if blocking mitigation has been increased from 20%?

The Blackest Night has pretty crazy scaling. It gains increased EHP based on gear and health, while other skills effectively lose it. Armor value increases base damage reduction, so the value of the other short cooldowns decreases as gear improves.

TBN will also become more of a detriment to damage output as the expansion wears on, it appears. It has already gotten to the point that people are eating tankbusters using TBN alone and still not managing to break the shield.
