No..it isn't. If the martial's superiority in combat niche requires DM cooperation to secure, while caster's superiority in the utility niche does not, it is a class design issue.Yeah. I'm not too concerned with encounter set-up for this discussion, though. If the DM is setting encounters up to make either casters or fighters king, and he can do both, then that's a DM issue and not a class design issue.
If I tell you you have the fastest car on the road, but only when you are going downhill with the wind at your back, if your car is underperforming, the problem isn't with the guy who designs the racetrack.
