Similar to what was done for the reconnaissance air unit, I think the interceptor should have its size increased as well. Compared to the other air units, they're too small and hard to make out and select. Once air battles get more intense, quickly selecting those interceptors is going to be important. And on the subject of unit size, reducing the size a bit of the reconnaissance air unit would be nice too - they look bigger than a Tier 1 unit, which is odd for what is basically a reconnaissance drone.
