so far i have 525 dust or something like that. should i save for a legendary and hope to get the rest of the couple dozen or so epics i need via card packs or should i wait on legendaries and craft epics first? i'm also worried about crafting a epic/legendary and then ending up getting that same card within a couple packs.
(the legendary i plan on crafting is either ysera, alexstrasza or golden deathwing. i really like the golden deathwings colors.
