The Testing Server should not be meant for infinite rolling nor should it be a gateway to do so. I've seen people literally join the Testing Server just to roll on equipment they'll never obtain otherwise.
The Testing Server is meant for actually testing what the developers want us to test, not to just sit in Haven all day complaining that "I didn't get the UVs I want in the Testing Server."
The only exception to bringing Punch back would be if you plan on modifying the system and would like players to test it.
Limit crown levels to 25,000 crowns, but have that 25,000 be infinite (I.E., it doesn't go down). This would allow us to buy all recipes in the game.
If that doesn't seem right, go to 35,000 so we can purchase from the strangers (3* items).
Don't remove Punch, but limit our money that we don't need.
