The first order isn't in a separate galaxy, they're in unknown space in the current galaxy. In the EU, the only extra galactic race that we see is the Vong, and I doubt Filoni is going to bring them in.
Thrawn would be anti First Order, and really anti-final order.
On the Ashoka thing, I think for those of us who watched clone wars and rebels we got spoiled by Eckstein and the animation style that bought her alive.
I would like an explanation on why this Ashoka is so dour, low energy and pretty negative.
I mean even after Anakin's fall to Vader, she was still the Ashoka we knew and loved. But the failure of Sabine's training couldn't have wrecked her so completely.
