Don't be heaters... Developers don't live from wind, they need resources (your money) to carry on developing the game and work on new patches and updates in general. In this case they said you won't get exclusive heroes, items, etc. from being VIP (Prestige in this case).
So camon, if you don't want to pay, that's fine, you can be a great player anyway! But
they have to monetize in some way their app, and that happens in all free mobile games. The case is that all of you are scared because this games works with VIP system, but I think this is not a conventional VIP system as they explained before:
YOU WON'T GET EXCLUSIVE HEROES OR ITEMS FROM IMPROVING PRESTIGE. That makes the difference.
PD: If the developer team improves the game and updates it usually, is thanks to P2W players, never forget that.
