This will not happen. The whole point of nobility was to have it as a special currency in which they could expand with (which they have) by giving it more uses than crystals. Nobility is a more powerful currency, therefor it is more expensive. Back in the day, there wasn't much to buy with them, but now we have seals, horns, keys for special chests, and even special spells. Giving nobility all that power, they would want to make it more expensive if anything.
Can you imagine how saturated with seals this game would be if they were only $1, the game is already saturated, but imagine how much more saturated it would be. There would probably be more HTE clans than regular ones. :lol:
Went to a clan the other day to drop a seal for them. They expected the seal I bought with my own cash to be FFA because it helps there clan out. That's why I have no clan loyalty to a clan that would steal from me.
