My last run was a couple updates behind, so I'll have to get cracking.
I'm guessing the Aghast is gonna be more satisfying with the new loadout mentioned. Might work it into fleets when I expect to fight Tri Tach, or use it as a mini Gryphon. Might also see more use now that Heg has the Grendel phase cruiser.
Atticus looks to be just another 'slot filler' for my early-mid colony doctrine where I'm cosplaying a random independent group rather than a functional polity. Looks prettier than usual, though.
Overall the Cumulus and Gallivanter are pretty solid exploration vessels. Their support versions have some extra points untallied, though.
The Adventurer seems like it could use a minor speed buff - it's painfully slow even with the 0-flux boost, and practically immobile if you have the fighters engage, and unlike the Nadir doesn't have the 'discount Paragon' ability of stacking range boosters and beam mounts.
Weapon groups probably need to be assigned better by default, though this may be a Nex thing.
