Still seems like a bad business practice to not post what the actual rewards are, or at least let others post it. Posting in a timely manner what the coming events are lets people plan how they spend their money, instead of them spending money and getting frustrated they should have just waited. And less frustrated people leads to less people quitting, which leads to more money for Oasis in the long term...

And only posting notes after the update is finished on some servers is not a timely manner.

Overall looks like a chance to save coupons, which I'm honestly glad for. I do wish their was more for F2P people, but at least there is seal rebate for people who have been waiting for that.
