Had a few friends with similar issues, they took a few months off, came back to WGT and they were a Legend with about 50 levels to go before they could buy the 'good stuff'.
No real solution except to play a lot, make sure you get your daily bonus, after a few days of playing it will max out at 880 points per day. I found the 18 hole weekly stroke play gave you points quicker than anything else. Unfortunately as you probably know, the higher the level the more points it takes to move to the next, I think I have been level 93 for almost a month now and still have over 60k to move to the next level.
