I could add another min-sized
tac squad by changing the paladin to an errant and dropping the inquisitor.
However, I just don't think it would be all that worth it in this list, to be honest. Right now, I think a core benefit of this list is that all of the scoring units (Knighte and the
tac squad while in the Raven) are largely immune to small arms fire. I do have a low number of scoring units, but they are all very very tough. One more min-sized tactical squad would be the focus of all the ant-infantry firepower in the opposing army. I don't think it would do anything at all and would basically just be 70 points that disappear into thin air
Adding anything more than one
tac squad would fundamentally change the list, breaking the formation or necessitating dropping a Knight and thus taking them as allies rather than a scoring primary detachment with 3++ Seneschal. I just don't see adding one or more troop choice to be worth breaking the Storm Wing squadron or the knights Primary, especially because losing the Knight primary means no more scoring Knights.
