I noticed on DPS Calculator that CDirk has the highest dps at 77+ DEF, but Etherite and Symbiotic Ripper do less than Cdirk (note that this is on Assassin). Etherite out damages Symbiotic at high def, but less than CDirk.
My question is, should I bother buying Etherite if Symbiotic Ripper does more damage at low DEF, and CDirk at high DEF?
