Long Live the Confederation!
The TCS Victory without Blair was, after all, "a second string backup carrier" that has not seen much "serious combat". Not exactly the ideal protector for confed last, best hope for victory. With Blair, however, it becomes an fearsome fighting force, capable of taking 5 Kilrathi carriers and multiple other capships, raiding Kilrathi prision worlds, and assaulting jump points on downtown Kilrah. Hey, Blair celebrity status even gives the Victory recognition within the Kilrathi royalty.
Again, I think you're missing the point - Blair didn't magically make the Victory a supercarrier. Tolwyn assigned Blair to the Victory and *then* moved the Victory to the front lines.
