that actually gives more reason to make them better if people are paying real cash to spin the dial then it should offer way better stuff
You missed the point. Being able to purchase spins for MC means players can buy spins - without the need for real cash. MC is bought with LP and those can be earned in game. The only true "real money only" roll is that single VIP roll per week. Sure there are probably players that pay for the LP, to buy their MC, but I don't think the game determines any difference between those and players that grind the LP in game.
Agree with OP though. Even if it is only one roll per week for VIP real money, they need to take out all the rubbish from that bag.
Sometimes, no matter how hard you look, there is no best light.
