I would like to suggest that Runes should be available in the shop to buy with coins. Several players have mentioned that they have more coins than they know what to do with. You can be in that situation after less than a year. The same players require 70 or more Runes to expand and it becomes a slow grind to progress. I think a price of 1,000,000 coins per Rune is reasonable. New players may not think so, but they will understand when they arrive at this point. I would be grateful if a Moderator could pass this to the development team. If nothing else, at least it would give S8's accountants a good laugh. Thanks.
