Second campaign is dead, at the hands of fucking Archons and a chronic understaffing problem colliding. I nearly clutched it out with my sole surviving sniper who would have saved three unconscious others, only for an Advanced Officer to finally get a hit on what would have been the last turn.
After that I entered the meatgrinder with only one surviving advanced rank. I sold off as much of X-Com as I could to get some fresh rookies only for the next mission to introduce Andromedons. Called it after the second code black.
Live and learn, I really needed to rush upgrades more heavily. I wish I had more time to play this game, avoiding my own thread is annoying.
Understaffing was the biggest issue for me in my Vet campaign. People would always come back from missions, but with, like, 22 days in the hospital. Then you gotta bring squaddies, and squaddies might crack, etc... I managed to handle it, but understaffing is just deadly all around. It's less problematic at least then in EU, since the GTS is easily the first or second thing you build, and you can start training rookies right off the bat.. You can buy two high-level units (one from headquarters for supplies, one from black market for intel) which is good for keeping your numbers up if they are slipping, but it is very expensive. Of course, better to have good units then dead ones in nice gear.
Unrelated, I wish I could actually set certain people as part of the A-team, B-Team, etc. It would be kinda cool. I think they have some ability as it stands to figure that out: my A-Team Grenadier went to visit A-Team Jane Kelly in the hospital (and would continually do so, which was cool).
