I know what your saying lilrob, it is boring, but I dont think 10yds further on average off the tee with a new driver results in driver/wedge golf for legends. Most likely it takes one club off. So instead of 3 iron or 3 wood into KIA 18, its 4 iron or hybrid, YAY.
The other option they can do is make it a risk/reward driver. Like most on tour that can bomb drives, they also can end up on the wrong fairway. Increase the length and decrease the accuracy. I dont mean speed the crap out of the meter, just make it less accurate then the other drivers. That will give people the choice of using it. With this logic, on a course like Bethpage, I would probably stick with my driver, but on a course like KIA, I would probably play the new driver.
I would say "legends" only, but I really think they should start moving away from the same teirs and towards tier attributes. Like a point system based on your player, it would be like the clubs, with 1 point of accuracy, 1 for distance, and so forth. A legend player lets say has 6 pts and can use those to increase their stats. i.e. 1.5 for distance, 1.5 for accuracy, 2 for spin, 1 for feel. If you want to hit booming drives, you are gonna have to load that attribute up, but you will lose pts in other attributes.
Its tier specific, and would be a reward to move to the next level, still facing the new challenges of that tier, but also gain something, attribute points.
