Potential gold sink - Purchasable Random Legendary

[clickeverywhere]

It'd make more sense if gambling allowed you to attain items ranging from normal marketplace items, crafted items, and legendary items. Of course, if this were the case, the base gamble should not be 4 million gold. I think overall the idea of being able to gamble for items is a nice idea for a gold sink. Of course, every time you gamble you should get something. If each push of the gamble button costed 5k gold, and the chance of getting a legendary were one out of a million, then... I can't do math. But the implications!
