Its kinda not fair that after paying real money i still get shit...also that 1 person will spend 5 E and gets drake and other will spend 50 to do it...if we pay it should be equal no randomness
It's all about your luck - some have it more than others. I spend 50 € in this sale (still have few keys left) but by far I have over 8k crystal chips, 38 boxes of all 3 different elixirs, almost 2 million gold dust, 20ish new costumes and 45000 gold in sold costumes I already had, lots of mirra, june coins, carnival masks and about 300 mount feeds... I also got Dragon, Gryphon and Viverne (wanted dragon and pegasus)...
Still, only thing I consider as **** as you called it would be gold dust since you can buy it straight with in-game gold. I would have paid many times over in real money to buy that many crystal chips on top of everything else! Previously I would have called mount feed as trash too but now that it's limited to 10 feeds per day (instead 110 possible with all incarns), I value it since it's not cheap and I have mounts to level up.
Meanwhile another completely new player didn't spend a dime and got Viverne from the Allods gift of few cards and compasses... Talk about luck right there!
So all in all, don't participate in Prophetic Card events, if you feel it's waste of your time/money. I dislike strongbox sales and I pass most of them or buy perhaps 1 to 30 boxes, if it's really tempting as Lightning Bolt mount, extra rubies or talent points etc. In my opinion strongboxes are far greater waste of money than Prophetic Cards ever have been.
Edit: got the pegasus too from lucky strike <33
