My biggest complaint is that there's really nothing for me to actually do with any of these things except go look at them (assuming I'm anywhere near the bubble when they release them). And there's no sense of people actually figuring anything out over a period of time like I think they're supposed to (I get the impression that Frontier intends for this stuff to last the entire patch, but players usually have it solved in a matter of hours). By the time I get home from work on the day the patch drops, there's already an ObsidianAnt video with every last little detail about the stuff.
Well yeah. The hope is that with 2.4 there will actually be activities to devote time to in the war effort. Maybe that even means passenger ships helping with evacuation or troop transports. Naval rank players being called into action by their associated faction. Explorers and haulers getting new colonies/temp colonies or new outposts/stations started. Smuggling or explorer vessels being refit and tasked as scouts for thargoid fleet movements. Sky is the limit really.
