I'm going to reiterate what donsprintr suggested.
Player tiers:
Master = the new tier for the e-lite players
Pro = The current master tier
Semi-pro = The current amateur tier
Amateur = The current hack tier
This tier system has a realistic feel to it. After-all, the goal at WGT is to be as realistic as possible, right? I'd like to see a qualifying round implemented in some way too.
I like YJ's response as well. There has to be a way for someone to earn their way into these tiers, and not through sandbagging. Will the playing conditions remain the same for all the tiers? What averages will one have to have to advance tiers? In any event, It's going to be very interesting to see how it all gets implemented. :)
