I second this idea, make or open a test server where players can play all features of the game .. For example, giving a starter pack that contains million of coins, thousands of coupons and ingots, Seal Scrolls and Summoning Scrolls .. Then have a special Ninja Fragments Shop that sells complete fragments of Treasure Ninjas and A Shop for Awakening, Upgrading Materials .. Then the other parts of the game will remain as it is, like the ninja exams and the instances .. So, the Test Players can try all the game features and see what and where the bugs is or the errors ..

And I know, if this Test Server will happen, it will be flooded with some other peoples that only wants to troll or whatever word is appropriate for that, tripping maybe .. So make this Test Server closed and only open for invitation, make a Test Server Hiring, and you guys are the ones who will provide the accounts to be used for the Testing .. The said accounts will also have a Time Limit, for example, for each Test Account, you can only play it for 100 days ..

And ofcourse, to make Test Players more observant and more serious with the game testing, maybe give them a little treat for their real/main accounts after the Game Testing ..

Having this kind of Server will benefit the players and the game itself, having a couple of hundred players for Bug and Error detection can help to polish and improve the game ..
