You still want to work on your EC. Obviously you will need 11k EC to buy the 20 required ear hats. I’m guessing that most of us will have enough EC to buy them the second chapter 3 opens. Then it’s going to be a 5 day mad dash to trying to level Jack Jack up as fast as we can. Since it appears there won’t be any EC gem conversion, we will want to make and spend as much EC as we can to buy the items required to keep leveling him up.
EDIT: Just looked and it only takes 1 hour to welcome Jack Jack, so some of us should be able to level him up fairly quickly.
Which just now gave me a sinking feeling that they won’t allow us to buy more items after welcoming him.
It would be fitting that they would do us and leve players with a bunch of worthless EC.
