I don't buy the excuse of "this is unplanned because players asked for it"
Fact of the matter is, MORE people asked for BA rebate for WEEKS, but that didn't happen. And unlike a middle of the week recharge event, a "surprise" BA rebate would not hurt anyone, because whoever wants that even is saving up anyway.
But no, instead you "listened" and dropped an event that is potentially harmful, that's just not sound logic.
That said, I'm a complete ftp, so this isn't bothering me any (other than the fact that ptw will get ahead even more, but I've given up trying to beat some of those so whatever) Still, I don't buy your story.
