The whole point of the Phantom was it's a very mobile ship that hits super hard and is extremely evasive, but dies super fast due to its low health. While the 2.0 phantom keeps its mobility, it loses everything else that made it special. It no longer hits notably hard, it gained a point of health but essentially lost two points of agility because it has no way to reapply cloaking during combat, meaning it's relying on two dice. Add the evade changes to that, and it has no way to stay in the game as it can't defend against either three dice attacks or swarms of two dice effectively.
On top of that, being dropped from four to three attack on top of losing key cards like FCS and Gunner means it doesn't hit particularly hard at all - many ships can hit just as hard if not harder now.
While I'm aware a lot of ships got nerfed, I can't see a single reason to ever bring a phantom now, as it lost everything that made it worthwhile, and all it got in exchange is a few points and a single health.
