I read from WGT admin's response that there are no plans to do anything about the legend tier issues at this time. A little disappointing.
The biggest gripe isn't the difficulty but the problem about trying to compete with the tour masters in situations like ready goes. If there was some way of addressing this I believe the difficulty would be less of a sticking point.
As I see it there are few options if WGT want to keep this new system of tiers and levels as it is (which I think is the case):
1) Introduce a Legend only driver - unlikely since that would be incosistent with the leveling system. Any new driver introduced would be unlockable at level 90ish and available to all.
2) Introduce a 300+ driver - more likely but will take many months for Legends to unlock and the same driver will be available to tour masters.
3) Introduce a 300+ driver and allocate experience points based on previous ranked rounds played - this would mean many Legends would get the chance to purchase the driver months before the tour masters, leveling the field for at least a while.
4) Drop the Legends back to the same tees as the tour masters - unlikely as this would leave only a small green speed increase as the difference.
I like option 3 best since it is the only one to allow WGT to remain consistent with the system structure they are working to.
Something I would also recommend is that higher tiers build experience points faster at higher levels. A Master and Legend may arrive at level 60 in roughly the same time but the legend can get from 60-90 in a fraction of the time it takes the master to do the same thing. This way the +300 yard driver would technically be available to all but practically only unlockable once Legend has been achieved unless you are willing to spend 24h a day playing ranked rounds for a month.
