I'd like to make a new suggestion about the kindred wheel It's not like I wanna QQ or anything but I noticed the amount of kindreds that is needed to spin the wheel is quite through the roof considering the items that are in it... Are the prices gonna stay like that? If yes, then I'd suggest putting items in there that are worth farming for, things like backpack expansion, stable expansion, lair expansion, chamber expansion, shard socket keys, shard binding agents, ...
Now I know you probably have to make up for all the marketplace dragons you are offering for free in this game, but what can we do with dragon eggs if we don't have a chance to store them or use them. I can already see you guys thinking "well, pay then and there's no problem" but the reality is that not everyone has at least 100 euros lying around somewhere to grab and say "oh hai 100 euros, I'll use you for stable and lair slots yippie ka yeey get me dem dragons". I say 100 because that's the easiest to calculate (it'd be 12.400 dias in total for stable, lair and chamber and we pay 100 euros for 13.700) that would be to unlock all spots for our dragons. Then we don't have anything else yet, like costumes and such.
A suggestion for your profit may be to keep all the items in the marketplace and to put all the dragons in it as well, that way you give people who wanna grind a chance and people who hate to grind can buy. That way, everyone can enjoy the game fully, not just the whales.
