It appears that there is only one modern light missile support hovertank out there at the moment, and it is a 40 tonner (Stygian/Hasasser II). Given that upgrading its engine, or switching to Clan tech could fix some of its problems, the question arises if the current BV environment could allow for such a tank to be worth fielding given all of the rigors of a modern battle? Is the Stygian the best that can be fielded for one's buck? I am aware of the APCs that can perform the task, but that is more incidental, as their primary task is more important.
PS It should be noted that Missile support hovertanks in the Inner Sphere should not have access not only to Clan LRMs, but also ATMs in addition to IS weaponry.
