Great for those that don't even have the unit...
That's the same case for all those that reset ips and make new accounts for getting dupes for maxing.
Can you lot not just get the codes for the ones that you are missing? Not rly fair for others...

/edit:
4th batch of Di Yu codes is out.
Finally managed to get a code, just by being weekend and having the possibility to stay awake longer
But srsly, they should change times for some batches.
