Let us just suppose, for personal reasons, I would like to completely restart everything.  How does one completely remove the game, purchases made, gold obtained, just everything.

 

On the IoS.

 

I have tried deleting the app, its data in gamecenter, my icloud backup, you name it. 

 

Thanks much!

You need a new account.

You get guite near manually deleting all groups and all characters.

I can understand removing your existing parties in story and/or quest mode to start new ones fresh, but why would you want to also remove your gold or purchases ?
