What's the thought on completing decks. My situation is, I have a good number of legs, although I would like sylvanas still, but the decks that I have the class legs, I'm missing multiple epics. I have grommash, but no brawl or shield slams. I have cenarius, but no ancient of wars. The decks where I have the epics I'm missing the class legs: voljin, jaraxus, tirion, antonidas. At about 1000 dust so could finish off the druid or save for a class leg. I guess my main question is, which class legs really aren't necessary to be competitive?
