I think it's a great idea as long as it is based on what you have accomplished like winning tournaments, shooting x amount of perfect rounds or perfect round on every course.
Extremely low average with x amount of rounds a week, etc etc...should be hard to achieve said status and must be maintained via current activity, no play no superstar status....if it is just based on Levels/XP points the idea sucks...
I would spend more money chasing a 300yrd driver than a higher tier if you want us to spend more!
I think you should get on that as soon as all the multi-player glitches and errors are fixed, and meter and disconnect issues are solved, The Brits and Scots get their flags, and for gods sake HPurey gets his Yellow Calloways...
Trust me, all of the above should be way ahead of a new tier on your "ToDO list"...
