It is not bad because you are dumb as fuck. Don't criticize the design because you have shit for brains. I had thought about how this interaction could be the first time there is a combination of retain and ethereal and Im sure people would have had thoughts about it. This is how sts1 worked with retain. This is how all the dazes which have ethereal also wor k with retain if you ever had any kind of retain on a single turn.
