I actually liken the idea of equips and pets and such being in a shop, but lowering the amount of NX you would get because people only spend it on cubes.
so if the equips, pets, and everything but the cubes was in a shop, the NX received after voting could possibly be lowered.
Whenever someone makes a new character they have to spend like 20k NX trying to get the outfit they want and the pet and pet equips they want. not to mention the store costing 1k.
Idk just my thought.
