Is Leeroy still used? As in, is miracle rogue still around somehow? Bought a 50 pack of classics, got Sylvanas, Ysera, Cairne, Golden Leeroy, all whom I was missing, and crafted a Dr. Boom with the extra dust, so I'm pretty happy with the purchase. But the Leeroy is tempting me. Still missing, out useful neutral legendaries:
Alexstrasza
Bloodmage Thalnos(maybe rogue?)
Harrison Jones
Justicar(only warrior and priest?)
Saraad
Ragnaros
Sneed
Maybe a few more should be on that list because I'm sure I'm not judging usefulness 100% correctly.
Side note: being able to play much more competitively in constructed just due to a few cards has made the game enjoyable again. Taking the pressure off arena runs being consistently infinite makes dealing with stinker drafts/runs much easier. Just go tool around in constructed for a bit to replenish the bit of gold you lost.
