ya i still play with it on mine. of course, x2 isnt BiS i dont think, but having one in the offhand is always nice and makes u cooler than rogues who dont have it (n u kno this man)
and yes EF all day, sub EF hemo spam does underratedly difficult dps to manage without having x2 healers/hybrids focusing on heals to keep the target alive
edit: actually not 100% sure whether dagger is bis mainhand anymore, needs someone who wants to do the math to test it to verify, also boa sword has comparable dps (better in some aspect but up to preference)
