It's the same Domino who specifically said there HAS been a change to rare drops, yes, and is looking at it this week.
The longer you go while crafting without having a rare event, the more likely you are to get one. There are no events guaranteed to pop up at exactly 35% through or any other number. Each round there is a chance of one, and the longer it's been since the last one, the better the chance.
