Hey all, new player here, just bought the game on steam and have been playing on my phone/computer.  I'm wondering what other people's luck has been like with buying/opening treasure chests. 
  
I know they aren't needed to win the game, I have been through once without them, but It would be fun to outfit my characters with these shiny gold bordered cards. 
  
As a test I opened up 100 chests with 100 runes and was very sad with the results, 4 total legendaries, all from adventure 1 and 2 (some shiny dice though).  And I wondered if other people had similar results when opening them, or did I have a run of bad luck?
