15? 20k? I haven't opened one of the crystals and gotten more than 4800 in gold so the gold rewards are closer to 10k than 15k. And you are right! as long as it happens in allignment with what i need and want to do (spending wise) it "just okay" but i can get the same stuff doing level up and rank up events. I will stick to those and pass on the gold spend. Not worth the possibilty of an extra two star to purposely spend a quarter of a million in gold just for this event.
