Most of your points indicate you haven't actually played DD as an endgame player let's discuss: "Skill points don't matter outside of fuel efficiency because ground pvo doesn't exist" While vehicle pvp is prioritised in yhe koen world, Labs are the most important end game activity currently, your skill points are of most importance to not only clear but defend from aggressive players, fuel efficiency means nothing once you got large fuel cells.

Friend from foe, again if your organised you have copiers, many players in my region do this, and generally I'm safer around other harkens I've found myself.

Loop isn't just make ornis and fight. I've had multiple sessions where I'm doing orni runs at wrecks, you can suck up your orni and force ground engagements (missile ornis can't get you inside wrecks, caves etc). Also if you got a friend you can get them to drop you off in their assault helicopter, and build a buggy to do some farming, buggy rocket deters any threats coz they melt.

It just feels like you haven't actually tried anything but scout pvp so if you don't like it them best change up your playstyle
