I have been playing more than 6 years and have to say that the 100% and 200% sale offers that some players get are a real sore point for me. I have NEVER gotten a +100% or +200% diamond offer, not once in 6 years. The only offers I see are the lame ones everyone gets for "get event currency when you buy diamonds". It is unfair for others to get diamonds to ease their play and get multiple event buildings at 1/3 the cost to me. Inno says it's random but it can't be random, not after 6 years of no offers. They have to code accounts for offers/no offers for the same people to get multiple 200% offers at the start of an event while others get nothing. And the new Castle System skews it even more - huge Castle rewards when you buy diamonds, so I will see myself moving down the player rankings, passed by players not as good or consistent as I am in every aspect of the game, just because they open their wallets for offers. Can't even use a new city bonus to add Castle points to my main.
Send a +200% offer to everyone, Inno, it is way past due.
