I still don't think the way the rangers dealt with LA was some huge plot failure. The only choppers they sent there were destroyed by heat-seeking missiles. Why would the rangers put all of their eggs into one basket by sending more choppers after their recon boys and ranger team echo were both shot down? I doubt they have the resources to pull more choppers out of their asses to deal with the threat in LA, especially when they didn't know the severity of it at the time. Echo one has likely proven themselves resourceful enough to find out what needs to be dealt with in the region and deal with it, though I suppose, like most things in the game that's pretty dynamic. A bit of reactivity to your success in the core region might have been nice, if you are really thorough and get the best outcomes they could send more resources to LA, not that it matters if it all gets shot down to shit. Maybe it'd just cause more complaining about "gimmicky reactivity".
I was really satisfied with my ending, felt very personalized, I left the Wasteland in a pretty wretched state, and not entirely on purpose. In Damonta I really needed to resupply so I abandoned the town to tend to my severely wounded rangers, causing the robots to massacre the remaining citizens, in canyon of titan I couldn't manage to clear the base of the Diamondback militia, so I ended up just sending the mad monks their nuke, seeing the canyon reduced to a crater was pretty great. I like how willing the game was to cut off so much potentially unfinished content with that. Overall my exploits in the Wasteland were very flawed and pretty terrible, but they were a result of my actions and were pretty dynamic outside of just my intentions.
I did purposefully aid in the restructuring of god's militia though, and their crusade at the end was glorious, even if I mostly did it to be contrarian. :D
At the end of the game I was ready to play again, but want to pace myself so I don't get sick of it when the big update comes.
