If putting was made easier on WGT so that the bad putters could become good putters, then what happens to the already good putters? Wouldn't they all become great putters and the already great putters wouldn't they all become super great putters?
So WGT has to keep a certain level of putting hard, that's the way it goes.
Often the players complaining the most about how hard putting is, are often playing at one or two tiers higher than they should be, that's their own fault for being in hurry to advance to higher tiers too quickly.
Learn to play better WGT or go play a cartoon online golf game, where every putts crashes into the cup with a loud ding, pop, wiz sound affect.
Same goes for golf clubs with more forgiveness. A club with a 5 forgiveness, would be boring. Miss shots by a lot and the shots are just off the pins.
