Might it not be prudent to wait for a period other than immediately after the release and a sudden high demand for collecting vast amount of seals, to decide if the system in place is sufficient or not?

Note: There was no problems before the Rank up requirement with 25,000 seals. (As far as capacity).

Also, any system you come up with anywhere will always have problems with people abusing/exploiting. Only way to avoid that is to go single-player game.

And finally, just because there are a few inconsiderate people out there please dont' suggest we should lock content in such a way that the end result is people like me can't play anymore.
