Soo.....why exactly are people so sour about the Raider's survivability against ships that are double -or triple- it's weight class? An ISD can one-shot a CR90 as well if you drive it nose to nose at it, but that doesn't make corvettes bad.
Bump up the blue dice capabilities of your Raider, and go after corvettes, or harry the flanks or rear or a Neb-B, and they can work just fine. I have two Raiders from early on, and sometimes feel like I out to try running them as a pair for such things, like I do CR90's in my Rebel fleet.
