I know this is an old thread, and since @otriux21 responded a lot has changed.
I have been actively working on building a side project, inspired by @otriux21's private server idea and have hit one stumbling block after another. I would LOVE to have a discussion with you @otriux21 at some point, as I believe you might be able to help me with a particular understanding of the game.
That being said, the use of memory modifiers, such as GameGuardian has come and gone as the game checks for memory signature updates and immediately restarts the game should any part of the application be modified before data is passed back to the server.
Kabam is definitely spending a lot of R&D on game security and proofing key aspects of the game from prying eyes, so much so, that we have seen a sharp decline in game play, user experience and stability but a sharp increase in defensive programming across the board.
If anyone is capable of building a mod similar to what MCOCmod has done pre-v12 it'll not be out any time soon, and will be kept under lock and key; similarly how @otriux21 and the team are able to release game play videos of new champs to showcase abilities and specials; think a private server used for private game play.
