This doerak guy or girl or whatever gave a valid suggestion in skyblock earlier.
What if there was a promotional discount in which donation rank prices were decreased by say 10% or something for a weekend or something? It isn't really much if you look at it this way; someone donating to obsidian is paying £150. With the 10% off discount, that's reduced to £135. That's still a heck of a lot, only it's reduced a little to make it seem more appealing.
Before you get the wrong idea, this could be either only availible to stones to encourage them to try out iron or lapiz, or could be for anyone who wants to upgrade from say iron to diamond with a little discount to make it seem a little more worth it. Just a random suggestion, as someone said that iron is a little expensive for them, and they aren't sure whether it's worth it. If the price was reduced to £9 for a weekend, the price tag is more appealing, and thus peopel will want to take advantage of this insane £1 off discount. What do you guys think of this? Would you like to see this kind of thing everytime that ccg reaches the donation goal or something, or maybe once a season?
