I dont see the use for this ability except that it makes you cc immune. It cancels if you use any other abilities so no reactives etc during 6 seconds. It crits for like 450 per mob at 44 which is not a lot. Its AOE but even with many mobs around its better to just spam our other aoe abilities.

Our final ability Destroyers bearing also seems kind of ****. 20% to all finisher damage as opposed to 25% to ALL crit damage. The extra chance for combopoints are not very useful.
