CC posted about it because a guy tagged him saying they were crazy. I had enough to do 6 AND still have enough for the full 98 BND. Results may vary but, here's how I did:
6 91+ BND ROH sets done:
1 99 Joe Thomas
1 91 Todd Heap
4 91 Jason Peters (lol)
Again, results may vary but for the most part, these seem to have pretty good odds. Probably because there's a finite amount you can do. If you get any good pulls post them for others!
