Its like the LT and C3. The LT can only shoot at targets it can see.
It's nothing like the LT and C3. The Long Tom doesn't come with its own see-everything-shoot-everything capability whereas the TBolt Sulla does (has its own NARCs). The LT without the C3 is basically useless, as LT shells have rather small splash, are easily defeated by cover (Long Toms can't really just fly around and shoot from directly above you), and have rather long travel times so mid to long-range engaging is a crapshoot at best. C3 is necessary to even
begin to describe the Long Tom as 'functional'. It basically mandates two people while TBolt Sullas do not. A Long Tom with C3 is an inconvenience. Two or more TBolt Sullas working together is GG.
The only arguments I ever hear used to try to describe TBolts as being balanced is that they 'turn really slowly'. Unless the pilot is a retard this is hardly an issue, actually, it might be a great asset. Whereas LRMs and other such missiles are quick and maneuverable (relatively speaking), this means that they'll immediately seek in at the point the NARC is at when they're fired. As the target moves, they'll try to follow it, which is why a unit running perpendicular to an LRM salvo will miss most of them or take the damage in the arm, vs. the center torso.
TBolts are NOT slow missiles (in just about every unit, they're fast enough that you cannot functionally do much besides jumpjet when you see them coming... even an Osiris doesn't accelerate
that fast). They do have limited turning, which is why you fire them where you think the unit is going. They'll try to track the NARC as usual, but because they can't whip around the back of the unit, leading a moving target will probably net you greater success than with LRMs, assuming you're good enough at it.
Tbolts are stupid powerful and not nearly the gimped weapons pilots want you to think they are. They do have their limits and for that reason I hardly think they're the most broken ASF weapon (that's reserved for FBombs). However what is broken is the fact that AA units are the slow, unmaneuverable kinds that are absolutely perfect for the passive NARC / quick-TBolt maneuver and there's no god damn way a Huit will ever be able to dodge a TBolt. This is why I support removing the NARC from the TBolt variants *or* reducing the NARC range to 200m, which necessitates at least two passes.
