Thankfully nobody's advocating for free callins here.
Eh, really?
Removing the fuel penalty just gives the callins a "sit tight and hold" doctrine, meaning the already cancerous turtling problem will get worse since the player would have no need to continually push into fuel/muni since he can just hold and wait for big boom vehicle.
Idk just my 0.02$ on why I am "against" callins in general as portrayed here.
