Kanan with Ezra gunner, dorsal turret, Magva Yarro, Chewie and sense can still mitigate a lot of damage with reinforce. Yes its 130pts but gone are the days of the cheap bulky house tank, that mentality for the Ghost needs to be thrown out.
My personal choice would be Hera with Han Solo gunner, Nien Nunb, and Ion Turret for 100pts. It goes against my theory that it must be decked out, but Hera can move well enough that she will dodge a lot of the damage Kanan would have to actively mitigate. I played Heragator quite a bit in 1.0 like this (no shuttle and no TLT) and she can move quite well. With her increased initiative and Nien Nunb's buff, she will be a lot more viable than before.
All in all yes the Ghost has taken a big hit, but its not useless. It was way overpowered to start with so we all need to adjust our expectations of this ship. I personally think the 2.0 Ghost feels a lot more like it does in the show, they've done well to try and capture that. In 1.0 it was just a face tanking turret mount with no flavour at all. I'm actually quite excited to get this ship on the board quite a bit in 2.0.
