ahhh dude that sucks. iv spent 80$ and got a TG, succ, champ, and pally. its really just about whether you are lucky right then or not.
I didn't spent a cent but running with 4 legendary currently. I wanted a succubus so bad. Wish I can exchange my extra druid for your succubus.
But anyway keep farming shards till u get did like how I do for my tg.
