hope your stuff is under control, kurt.
idk about "conservative", the humans get to pick their poison. feel the humans would rather get astrogation data than a pitched battle right now, esp with training to be done and so little of coalition economic power properly in the harness as yet. i even wonder, based on the small size of the d'bringi fleet, if the humans aren't better off in an assault than an open space battle, regardless of the fleet doctrines. otoh, the prospect of a passel of roaches showing up is a shrivelsome one.
playing burnout games against a smaller, higher grade fleet is godawful. ive won a war from getting d'bringi's side of that trade. look, the humans are going to have 3 or 4 ships put out sick for a minimum of 2 months for each ship they kill. if there's enough of that action to matter, the margin for error in an assault plummets. it was a small pile of IDEW won the day for me, and the humans gotta figure the D'Bringi have more mines already in transit.
tricky for the coalition to fight this war sensibly without restoring the russians to a position of being more dangerous than the d'bringi currently are. at the minimum, they need to put substantially more fortifications on the sol WP than the russians have, post haste. keep feeding Russian cruisers into hostile WPs, and then present them with an arms race as soon as the current war ends. refuse to open negotiations for recovering those russian colonies ("we can't risk another conflict right now!").
or, you know, sell the russians some rope. on credit.
