To me, WGT is like any regular bank; you can be a member & use their services only if you mean good business (money) for them. You, or your ideas do not mean good business for them, you can write a full "bible" about suggestions, personal preferences, new challenges, etc, but you will certainly not change a thing!. Credit makers here will just make more & more credits NOT at expenses of WGT, but at expenses of regular "mortal" players...or naive ones, just to be polite.
....just saying.
I don't understand your point. If WGT is a bank, it wants your money. It will get more money by having more people play in more RGs. They earn their money by taking a percentage of the entrance fees -- it doesn't who it comes from or what their scoring average is.
WGT should want as many people as possible playing in ready gos, especially "new blood," ie, not top earners who are just giving and taking credits from each other (while WGT skims its percentage).
That's why they introduced tier-based RGs not long ago ... but obviously it's not working out so well for the legends who don't shoot 27 every time they play.
