I'm curious how you're getting 80k absorbs, your gear must be amazing.

I tested myself now, not fully geared but:

45% PVP Power vs 55% Resilience player

Average NS absorb - 24-29k
With trinket + pillar of frost + fallen crusader - 45-50k

This is based off of the tooltip on the affected player, not sure if it's accurate. On a target dummy I am hitting about the same numbers :/
