I hear what you are saying, but what I think is going on is WGT is trying to make the hack and amateur tiers real.
Even with the moved advancement averages for tiers, most (all) players are through the Hack tier before they even know what is happening (except the winners of the tournies....don't get me started).
The amateur tier only exists until you posted 14 rounds and received a real average (Show me 3 people in the amateur tier with 20 posted rounds).
We have to remember that this is a BETA game and they will make things different to make the game better for market.
We will sometimes get caught in the crossfire of this development stage (all of a sudden in a tier that we cannot deal with).
Don't get me wrong...I think there are some major issues that need to be addressed (meter,courses) and I don't think WGT is infallible.
Lets just play golf and enjoy the ride.
