Playo's level rewards are practically nothing!?

It makes me sad playing since the beginning. After the management changed, they stopped giving out rewards all at once, but at this point, honestly, the rank perks aren't even a little bit exciting. There's no noticeable change. Also, separately, I personally want them to fix the app lag that happens right after the date changes – it's quite bad. Maybe they're cutting back on servers and stuff to try and save money, lol.
