One of the basic tenets of a good game is that the rules are fair and clear. When the rules are different for some people as compared to others, that’s when feelings of unfairness set in. In this game, I believe that it’s creating a situation where people feel it’s unfair and they’re getting slighted because the “rules” are different…some people are intentionally offered better deals than others.
This creates a no-win situation with the developers long-term. If the big spenders are offered the better deal, then the low spenders feel slighted and that this is a pay-to-win game. If the low spenders are offered the better deals, then the big spenders wonder, “why am I spending so much money, then?”
Just some advice to the developers…make all the deals available to everyone. It’s easier on you, everyone thinks it’s fair, and it avoids this no-win situation for you.
