''Mark is right from A to Z'' - LMAO indeed, haha!
''The premium tier is only cosmetic stuff'' - This is a direct and unedited quote by Mark.
You're claiming this is true? In that case you're playing a different game than I am. Then again, you did mention the extra XP, so it would seem that you are also contradicting yourself. Does the Premium tier reward you with XP? Yes or no? It does in my game, which in turn proves that ''Mark'' is factually incorrect.
Speak for yourself, I'm Level 94 and need XP to improve my golfer's skills. Also, why would you need more than one golfer? If you want more challenging rounds, that can be modified in the options. Genuinely curious.
