you can't fight with ONE debuff running on you ? look at that :
trader 200 : 9OO atk rating
X prof 200 : 1150 atk rating (not all profs, I know)
then trader divest X
trader : 1050 atk rating
X : 950 atk rating
in mass pvp, that doesn't mean you are "out", you won't even be OE
that's the 2nd drain that totally ruin an opponent, not the first one, and most of the time our plunders are resisted, especially on casting profs such as docs and NTs
doc can still heal, NT can still blind/root/nuke, not as good as he's used to but he's not "out"
AND mochams can just counter a deprive's effect (for nano-skills)
with one divest running on me, I'm not OE, I can still root/heal/debuff/shoot, I won't zone or run out. With divest+plunder yes I'm out, but it's damn hard to plunder me if I'm on full def with 900 NR
