About Elemental wand

How is it scamming?
It's true Nexon never did say that there will be the elemental properties. They never forced you or asked you to spend money on gachapon to try and get the staff/wand, it's completely up to you. (Well, the users of Gachapon trying to get the staff/wand)

Imagine you go to a coke machine. You put your dollar in, select the type of pop you want and it comes tumbling down. You put your hand into the little door thingy and grab your can, only to realize that it's empty. Frustrated, you call customer support. They brazenly tell you that that particular machine is behaving as intended - they're only selling empty, unopened cans at this particular machine!

The machine never told you there was going to be liquid in that can, right? It's implied and understood, just as it should have been with these staves/wands.
