no, we absolutely do not make clubs worse to upsell new ones. never happened.
I'm not sure if this is more of the 'legaleeze' that we have, sadly, grown accustomed to from the mods. But if the qualifier "to upsell new ones" is removed, then my experience says this statement is total hogwash.
For instance, the forgiveness of my L100....er, L95..Nike Vapor irons has most certainly been altered. While the results of a misding haven't seemed to affect shots laterally, misdings that used to cost me 4-5 yards of distance now cost me 10-20 yards easily. I've noticed the same effect with my L76-80 CG16 wedges as well.
There are numerous other examples. Of course I've long maintained that the game plays differently for different players and, as such, your results may vary. These are just my observations.
