xDacon, we want to give you our money—we really do; you just gotta work with us and make these keys more worth our hard-earned cash. Here are some ideas I came up with just from a quick brain-storm:
1. Make an "Enchantment Crate" that has enchantment books in it.
2. Make a "Spawner Crate" that has spawners in it.
3. Give us more keys for the current prices & people will buy way more keys. (It wouldn't inflate mana/in-game money because the prizes are not that valuable right now.
4. Add seller/collector minions to crates.
The current cost|prize ratio makes people not want to buy keys, even if they have the money to do so.
