So, as much as I love the Raider, aesthetically and for its idea in filling a role in the Imperial fleet, I sense some problems with the little thing.
In the case of the CR-90, you have a small ship that doesn't have much defensive bulk. However, it stays at decent range where its evade tokens can actually keep it alive fairly well.
The Raider, from what we've seen so far, has a problem. Its attack dice all seem to be short/mid range, but its defense dice are two evades and a brace. Our inherent problem is the Raider has to get in close to do its best damage, but when it's there, it's open to counter-attacks. A single "aim" result will remove its brace, and its evades are useless at short range, so any damage you take will be straight up the a**.
Unless the Raider comes with some sort of upgrade to its evades, or some way to make itself more sustainable, it's going to get ripped apart, unlike its counterpart, the CR90, who can stay far away and troll around the edge of the board.
