I would think Brutal & Moon would beat crit earrings myself. The dagger isn't to good cause it lowers DPS to much to be worth using for WS alone.
They do. Moon is basically crit hit+ and Brutal increase's chance for DA on first two hits. Str Sword is your best off hand for it unless your at capped attack.

RDM's DEX gear is ~blah~, it's not bad but it really does need more. RDM should of been on Toci's / Athos but Tanaka in his infinite wisdom things RDM is "a very powerful job" and put it the gear set that is completely useless to RDM. Not much we can do about it for now, once gear is released SE is incredibly resistant to changing it. Their releasing new Morrigans gear and that's what I'll be looking forward to. Though honestly, Mercy Stroke should be pretty good with some of the Dux+1 we can get. 3.0 fTP with two hits, 60% STR and 40% damage boost to go with it's extremely nice DPS and enspell effects.
