This was the clue he gave us

Here is a huge Clue for you guys as I do not want to be the one responsible for Bans and account resets. I hope you can understand but if not then feel free to hate as that is what the internet is for anyways right? When I found this glitch I was doing the same legend glitch and chose Pathfinder. As you notice the glitch did not work correctly and made me Octane once in game (but at the end you will see pathfinder bonus reward as I had first chose him). So the key here with my method is that you need to either follow steps from that glitch and figure out yourself or Figure out when exactly to suspend the game
That is all I am going to say for now on this glitch and hope all can understand as I do not want to get others banned or reset, if the game was in a Beta I would not mind so much. But many kids will use this not thinking of the consequences. Here is the video for the same legend glitch if you have not already seen it - https://www.youtube.com/watch?v=tu24-H9Vim4

Use at your own risk.
