Threat and you
When generating threat, it is good to know what skills and abilities generate the most thread. The currently accepted level 70 threat values are as follows:
Notice that it only makes sense to use Devastate when your Devastates hit for at least 200 points of damage, otherwise it is better to just use Sunder Armor from a Threat point of view!
EDIT: As Nokozon pointed out in an email to me, a little more info on Devastate damage.
… that with five sunders the damage from devastate is increased by 165 damge without the 50% weapon damage this is because devastate gains a extra 35 damage from every sunder that is applied to the target …
Thanks for the clarification, Nokozon!
