Agree about everything besides Armor. Its bad even against fighters. Cuz its shoots not very often, and AI have no clue about it anti fighter role. And then i personally command it and use it in best case scenario - vs swarm of fighters, its anyway feel inferior to simple destroyer with 2 dual flaks or something similar, lol. Against stripped armor - its still inferior to everything else, cuz minimum armor + small damage per pellet + missing pellets.
Imho to be useful in this role it must have much, much better rate of fire. Especially in AI hands. Or maybe its better to increase number of pellets (with every of them deal less damage, so dps remain the same) but make them guided? So they will be better at hitting fighters, and then used vs ships they actually hit them.
Im not sure how, but im sure what armor package effect need some love to be useful.
Also about elite flux management - vs atlas yes, its better. But in fight worse shields and range make him to take more flux. Its ok in small skirmishes, but not better to no-package build, so why take the risk? Maybe slight buff to elite dps? I know what all elite builds made to be more dangerous, but usually its give something great in return. Like with those rocket cruiser, which is suffer from both penalties and bonuses of elite package (for example better flux generation make him eager to charge onslaughts and paragons). But this elite rockets just awesome and worth all the troubles.
Meanwhile, targeting on Libritor is okay. Not as good as targeting on missile-bot (kinetic rockets is always awesome), less dps, especially vs nimble targets, but this package make this ship super safe to use, due to huge range. And in big fights even if he miss main target - he will hit something anyway. So after several dozens of battles, and 4 lost Libritors im stick with targeting and no-package.
Anyway i enjoy this ship, really cool design!
