Scion for a starter?

Scion was pretty strong once upon a time, but they nerfed it pretty hard and it never really recovered. Now, at best, is 2nd or 3rd best at whatever your building, usually worse. Probably why it's getting a new ascendancy option; new ascendancies are hit or miss and they didn't show enough details on it to even have a clue yet. That said, I'd watch for the drop of the full ascendancy details and see what people think can be built with it. But you're usually getting that info day before launch, without much time to theory craft.
