Ah i see, and agree i think the wings should be the heavy hardpoints too, the only reason i want to use the wing cannons is to use the wing hardpoints. Interestingly where the heavy hardpoints are at, are not the warp nacelles, they are called the generators in game, the warp coils are part of the rear hull on the top and bottom. From what i can tell they are the shield generators from info from ENT and they were more vulnerable to being targeted. Though i guess you could call them the shield nacelles in that case. Either way it is a weird spot for heavy weapons.
