I have a suggestion that will make the game more beatiful...
Make the possible to exchange/gift items please many people want it.

This has been brought up and knocked down many times.

A player could keep creating multiple accounts, grinding to a certain level without purchasing anything. Once they reach that level they could buy however many item boxes they can and transfer all the good stuff over to the main account. In a sense it's classed as farming.

Well make it for level 30!! There is no more 'nothing to say
I don't think that someone do this with level 30 it makes no sense to create an another account if to exchange items you must be level 30.
Anyway it's always good if in this game you can farming.

make it possible for you to only gift an item every 1 hour and then there would be no farming like you could only gift to other people once an hour or day?
