Going by spreadsheets, DB falls far behind Req, KoR, and CDC, even with Mythic and AM3 up it still has a lower DPS than any of the other WSs, that is the only reason I did not bother with it. I do however have a set for it stashed away on my spreadsheet because I am planing to make the Mythic someday just to complete my collection of RDM weapons, even if it is stupidly worthless.
