I too like the idea from YJ. The problem as discussed in the past has been the time frame, with WGT saying players would lose interest.
A shorter time frame woukd work but would lose some impact of the idea. I cannot see the problem of the longer time frame, and use points/earnings as per real professional tours. Then the top x amount of players could play for a season finale tournament. This way there is no pressure to play all events, but obviously would be to your advantage to do so.
I am pleased that ideas are being asked for, as quite simply, Nation Membership has meant nothing to members as there have been no real benefits.
I like the ideas of special offers to Nation members but could I propose that Nation members can rent a club and if they elect to buy within a certain time frame, get this deducted of the purchase price(personally I think this should be across the board). Most Nation members have good clubs and this would be one way of coaxing its members to upgrade. Perhaps also some Nation Only equipment (balls/clubs) etc
