You have played 16 rounds according to your stats, and NO match play, meaning you have not played with other players who could possibly give you advice. I have never hit a straight putt that ended 4 ft of course, and since I have played many more rounds than you, I can say I think you are exagerating greatly. If you are correct, did you save the shot? Did you report it? Did you do anything to help WGT respond to your situation?
Do you expect to shoot sub 70 without putting in the time? Can you hit a bunker shot in real life withe anything less than a nice solid blast? Perhaps you are aware of the flaws but not taking the experience from them. If you are 10yds away, hitting a 60yd full swing, are you taking the shot to like 15% power, it wont work, its to light a hit, just like in real golf. You need to blast out of most bunkers. I take a 15yd bunker shot in real golf, with more power than I do for a 50yd shot from the fairway.
Nothing personal, but if you are not gonna practice different shots to see what works, play with other players and see how they play, and even get advice from them, then dont expect to win the free tourneys, or any ready-go's, its not gonna happen, especially with the unlimited tourneys. If you want to be competitive, practice, win some credits and upgrade your clubs, then learn those clubs. If you have a couple bucks to spend then do so.
Does this game have bugs, ah yeah, put they are trying to fix them, its still in beta mode, and part of being a member hear (in my opinion), is to help them make a better game through reporting issues.
