I edited because in pvp if people stack DR then maybe +80ed would be better. But if we talk only about pvm, then -10 is much better because thanks to your skills, stats and auras you maybe already have 1000%. But changing a monster resistance, for example to the urdar in the pic before, from 55 to 45 will increase your final damage far more.
-10% is far more superior than 80 Ed
Sounds good. That's what I had in mind but didnt know if there's like a limit to how much negative physical resist we can apply on monsters.
Sounds like I need to get a sunder charms soon to boost more dmg
