Given that HP scales linearly with level, damage should too, at a similar rate. It's the only way to avoid HP bloat, and progressively longer and longer combats, at high level. Well, either that, or abandon scaling HP with level, which is a good approach, but one that wouldn't feel like D&D.
Every class should have significant damage scaling with level. I could see turning CS into a sort of "base damage bonus" that all characters get, with smaller class-based bonuses layered on top. But if Fighters don't get CS all to themselves, they'll need something else instead.
