Yeah , unfortunately that was changed when there was already a player lvl 21.
The thing is VIP is brand new and it was supposed to be adjusted and most likely will be adjusted.
The way cashback was working , it apparently , made the player's advantage over casino too much so both the mechanics of it and the level requirements had to be tuned to avoid the casino going bankrupt in the long run.
Again I understand all of this, I have many years in dealing with real world casinos and online poker rooms. If you give away the farm there is nothing left.
What I am talking about there is a term for it. "Bait and switch", now I do know admin did not have malicious intent when doing what he did, traditionally a bait and switch has malicious intent behind it.
Traditionally, when you have a promo or in this situation rolling out a beta update, if something is wrong you compensate the people that were involved in it (make things right).
Again I don't know if this is correct, from the weekly contest I can tell at this moment there are only 3 players that have met the requirements for lvl 21 or more. So making things right shouldn't be to complicated.
And in the future it might be in your favor as a business, if you are changing the terms of your perk system, notify the participants that it will effect. Just letting someone stumble upon it is not a good sensation.
