Well I had 4 vortex now, 3 mythicals used, hundreds of other souls used. Only 1 new character (gunner pyro.)
Next I tried to get gunner minotaur. I used 19 heroic souls, 3 legendary heroic, and 2 mythical heroic souls. Guess what: 3 beast eddie duplicates.
Next event I am due to pull the featured character in the first soul I use.
Gotta think positive. How has your luck been?
