Sundering Strikes is CRAP
Although most traits do have some purpose, you are right, this one is complete crap. I think they meant to have it apply 5 stacks of vulnerability for 5 seconds or something, but right now it is the most useless trait I’ve seen and does need some help.
The only save I can say is against big boss targets. You’re not going to be Mugging that boss every 45 seconds right? If you have high crit, you can maintain 2-3 stacks of vulnerability.
Mug, say, 2000 damage every 45 seconds – ignore the stolen item because it’s the same regardless of build.
So it ends up being 44.4 DPS increase. Pfft!
Sundering Strikes against a boss mob, maintaining 3% increased damage, with 20-30 people doing 1000 DPS each.
This ends up increasing the damage output of a large group to a single target by 600 DPS.
For you solo, doing 1000 DPS, you will gain 30 DPS, with the added benefit being as soon as any other player is attacking your target, they benefit, gaining 30 DPS per person who is attacking your target using this model.
SO!
I take it back. Learn to play noob! This skill is AWESOME for multiple people hitting one target!!!
