Unlock your gachapon box event

An average player doesn't have to be an NX user. So IMO: having both a box AND key cash items is no different(or can be).

WHAT ARE YOU TALKING ABOUT

I'm talking about THE ACTUAL BOXES. You don't need NX to get BOXES from MONSTERS, and you can sell those BOXES for MESOS. Nexon didn't need to allow this, they could've easily just sold the BOXES themselve, eliminating the middleman and making the profit entirely for NX users and themselves.
