I'm hoping you are right.. there are some precedent for the extra armament - The Phoenix has both turrets and supposedly a PDW at some point, the E1 has both turrets available to that chassis. I do like the Phoenix but would welcome a newer design.I'm still of the belief that the ST is for priority transport, and that the extra turret is for the protection of VIPs.
I guess only time will tell. if we never hear anything about the ST ever again, then it's been scrapped. but if CIG do bring it up a few years from now, then we will learn what it's really for.
it's pointless to speculate now.
CIG's game design of creating predator and prey (more or less by ship class) annoys TF out of me at times. The Zeus lineup is an excellent example; MR has both turrets 'for combat'. The CL which is expected to carry valuable cargo is nerfed, and the ES which is meant to operate independently in the black is BLATANTLY nerfed, it has nothing in the upper slot.
But speculation is fun, and burns calories.
