The M3-A Interceptor has struggled in X-Wing. Due to its fragile nature it simply cannot compete with the other options available. The Light Scyk title comes at a 2-point reduction bringing it into line with the entry level TIE Fighter and Z-95 Headhunter options allowing the Scum to have a cheap expendable fighter.
The Heavy Scyk title gives some flexibility in arming the Interceptor and a hull increase however it doesn't escape the fact these ships and simply vanish after a volley of fire. That being said, they can also be the cheapest Heavy Laser Cannon platform in the game so they can certainly have teeth of their own.
