Good master and tour master players have a huge advantage over legends in regular RGs. You have the same clubs or close too what we use.
I just started playing RGs in Feb or March when I was a TM. I had MANY more top 3 finishes and wins for that 2 or 3 weeks as a TM before I made Legend. 4th place through like what 10th or something pay the same anyway and you still gain 100 credits.
Careful what you wish for, though. You start winning and placing top 3 in RGs and you'll be a legend about 2 seconds after your average score goes from 61.1 to 61. And yes, this includes your tier tourneys. I know because I used to play the TM tier tourneys and it took the same low scores to win those as it does to win regular RGs.
