Yeah, i have nowhere near 400 rounds.... and I'm legend. I have nowhere near 200 rounds. I wish there was something written in stone instead of people just making up their own rules on what is required to be a legend
I'm sure that the rules are firmly printed in the game's programming code, it's only that we do not know all of it.
By strokeplay and without any extras, it's 150 rounds minimum to become a Legend.
Your extras were 20,000+ credits in winnings and 17 match wins against Legends. The stones said that you were too good to stay a TM.
Congratulations!
