Iron jaws & potency

[AniCelestine]

IJ actually offers a pretty hefty DPS increase because you can get two sets of buffed dots whenever you use CDs and you don't have to clip horrendously early as you would for that if IJ didn't exist.

And correct me if I'm wrong but using one 100 potency was it? Instead of 2 under 100 potency initial hits to reapply dots is in itself a dps increase already
