I was wondering if Alpha Testers could have a reward for playing.

Will there be a wipe-out in OBT?

This is closed beta, but yes there will be a wipe (oh dear us who spent all that time grinding despite knowing this) and yes there will be a reward although someone else will have to point out what they actually are since I don't quite remember.

the rewards are 10k exp a bunch of soul eggs, some money and an accesory

I do hope that there will be another reward for reaching Kyoto.
